%%% year is a 4-digit number, and abbrev is a
%%% 3-letter condensation of important title
%%% words. Citation tags were automatically
%%% generated by software developed for the

test both the preference and accuracy of high
dynamic-range (HDR) rendering algorithms in digital
photography application. The goal was to develop a
methodology for testing a wide variety of previously
published tone-mapping algorithms for overall
preference and rendering accuracy. A number of
algorithms were chosen and evaluated first in a
paired-comparison experiment for overall image
preference. A rating-scale experiment was then designed
for further investigation of individual image
attributes that make up overall image preference. This
was designed to identify the correlations between image
attributes and the overall preference results obtained
from the first experiments. In a third experiment,
three real-world scenes with a diversity of dynamic
range and spatial configuration were designed and
captured to evaluate seven HDR rendering algorithms for
both of their preference and accuracy performance by
comparing the appearance of the physical scenes and the
corresponding tone-mapped images directly. In this
series of experiments, a modified Durand and Dorsey's
bilateral filter technique consistently performed well
for both preference and accuracy, suggesting that it is
a good candidate for a common algorithm that could be
included in future HDR algorithm testing evaluations.
The results of these experiments provide insight for
understanding of perceptual HDR image rendering and
should aid in design strategies for spatial processing
and tone mapping. The results indicate ways to improve
and design more robust rendering algorithms for general
HDR scenes in the future. Moreover, the purpose of this
research was not simply to find out the ``best''
algorithms, but rather to find a more general
psychophysical experiment based methodology to evaluate
HDR image-rendering algorithms. This paper provides an
overview of the many issues involved in an experimental
framework that can be used for these evaluations.",

positions using active motion. The PIP (proximal

in Exps. 1--3 and the MCP (metacarpophalangeal) joint
in Exps. 4--6. In Exp. 1, the just noticeable
difference (JND) of PIP joint-angle position was
measured when the MCP joint was either fully extended
or halfway bent. In Exp. 2, the JND of PIP joint-angle
position as a function of PIP joint-angle reference
position was measured when the PIP joint was almost
fully extended, halfway bent, or almost fully flexed.
In Exp. 3, the information transfer of PIP joint-angle
position was estimated with the MCP joint in a fully
extended position. In Exps. 4--6, the JND and the
information transfer of MCP joint-angle position were
studied with a similar experimental design. The results
show that the JNDs of the PIP joint-angle position were
roughly constant ($2.5^\circ$--$2.7^\circ$)
independent of the PIP joint-angle reference position
or the MCP joint-angle position used (Exps. 1 and 2).
The JNDs of the MCP joint-angle position, however,
increased with the flexion of both the PIP and MCP
joints and ranged from $1.7^\circ$ to $2.7^\circ$
(Exps. 4 and 5). The information transfer of the PIP
and MCP joint-angle position were similar, indicating
3--4 perfectly identifiable joint-angle positions for
both joints (Exps. 3 and 6). The results provide the
basic data needed for estimating, for example, the
resolution of fingertip position during active free
motion. They are compared to the results from previous

behavior, we will need to understand its basic
components at an abstract level. One way to achieve
such an understanding would be to create a model of a
human that has a sufficient amount of complexity so as
to be capable of generating such behaviors. Recent
technological advances have been made that allow
progress to be made in this direction. Graphics models
that simulate extensive human capabilities can be used
as platforms from which to develop synthetic models of
visuomotor behavior. Currently, such models can capture
only a small portion of a full behavioral repertoire,
but for the behaviors that they do model, they can
describe complete visuomotor subsystems at a useful
level of detail. The value in doing so is that the
body's elaborate visuomotor structures greatly simplify
the specification of the abstract behaviors that guide
them. The net result is that, essentially, one is faced
with proposing an embodied ``operating system'' model
for picking the right set of abstract behaviors at each
instant. This paper outlines one such model. A
centerpiece of the model uses vision to aid the
behavior that has the most to gain from taking
environmental measurements. Preliminary tests of the
model against human performance in realistic VR
environments show that main features of the model show
up in human behavior.",

generally worse after imagining locomoting and for
greater degrees of rotation in perspective; they did
not differ significantly across knowledge derived from
exploring the physical versus virtual environments. In
the second experiment, subjects were asked to imagine
simple rotations versus simple translations in
perspective. The errors and latencies indicated that
the to-be-imagined disparity was linearly related after
learning the physical and virtual environment. These
results demonstrate functional similarities in access

evaluate the performance of the display. The first
experiment compared the ability of subjects' to
identify various materials, which were presented
physically or simulated with the thermal display. The
second experiment examined the capacity of subjects to
discriminate between a real and simulated material
based on thermal cues. In the third experiment, the
changes in skin temperature that occurred when making
contact with real and simulated materials were measured
to evaluate how these compare to theoretical
predictions. The results indicated that there was no
significant difference in material identification and
discrimination when subjects were presented with real
or simulated materials. The changes in skin temperature
were comparable for real and simulated materials and
were related to the contact coefficient of the material
palpated, consistent with the semi-infinite body model.
These findings suggest that a thermal display is
capable of facilitating object recognition when visual
cues are limited.",

abstract = "High-fidelity image synthesis is the process of
computing images that are perceptually
indistinguishable from the real world they are
attempting to portray. Such a level of fidelity
requires that the physical processes of materials and
the behavior of light are accurately simulated. Most
computer graphics algorithms assume that light passes
freely between surfaces within an environment. However,
in many applications, we also need to take into account
how the light interacts with media, such as dust,
smoke, fog, etc., between the surfaces. The
computational requirements for calculating the
interaction of light with such participating media are
substantial. This process can take many hours and
rendering effort is often spent on computing parts of
the scene that may not be perceived by the viewer. In
this paper, we present a novel perceptual strategy for
physically based rendering of participating media. By
using a combination of a saliency map with our new
extinction map (X map), we can significantly reduce
rendering times for inhomogeneous media. The visual
quality of the resulting images is validated using two
objective difference metrics and a subjective
psychophysical experiment. Although the average pixel
errors of these metric are all less than
1\%, the subjective validation indicates
that the degradation in quality still is noticeable for
certain scenes. We thus introduce and validate a novel
light map (L map) that accounts for salient features
caused by multiple light scattering around light
sources.",

facial expressions are stylized using three common
techniques (brush, cartoon, and illustrative

experimental measures. Going beyond the usual
questionnaire approach, these experiments compare the
techniques according to several criteria ranging from
subjective preference to task-dependent measures (such
as recognizability, intensity) allowing us to compare
behavioral and introspective approaches. The second set
of experiments use the same stylization techniques on
real-world video sequences in order to compare the
effect of stylization on natural and artificial
stimuli. Our results shed light on how stylization of
image contents affects the perception and subjective

the local image contrast by controlling the local image

contrast enhancement as an optimization problem that

abstract = "This paper describes the use of desktop and immersive
virtual environments to study judgments that
pedestrians make when deciding to cross a street. In
particular, we assess the ability of people to
discriminate and estimate time-to-contact (TTC) for
approaching vehicles under a variety of conditions.
Four experiments observing TTC judgments under various
conditions are described. We examine the effect of type
of vehicle, viewpoint, presentation mode, and TTC value
on TTC judgments. We find no significant effect of type
of vehicle or of viewpoint, extending prior work to
cover all views typically encountered by pedestrians.
Discrimination of short values for TTC judgments is
generally consistent with the literature, but
performance degrades significantly for long TTC values.
Finally, we find no significant difference between
judgments made in a desktop environment versus a
head-mounted display, indicating that tracking the
approaching vehicle with one's head does not aid
discrimination. In general, people appear to use
strategies similar to those that pedestrians use to
make real-world, street-crossing decisions.",

human vision that allows us to efficiently and rapidly
analyze our surroundings. Several studies have explored
the processes underlying human scene categorization,
but they have focused on processing global image
information. In this study, we present both
psychophysical and computational experiments that
investigate the role of local versus global image
information in scene categorization. In a first set of
human experiments, categorization performance is tested
when only local or only global image information is
present. Our results suggest that humans rely on local,
region-based information as much as on global,
configural information. In addition, humans seem to
integrate both types of information for intact scene
categorization. In a set of computational experiments,
human performance is compared to two state-of-the-art
computer vision approaches that have been shown to be
psychophysically plausible and that model either local
or global information. In addition to the influence of
local versus global information, in a second series of
experiments, we investigated the effect of color on the
categorization performance of both the human observers
and the computational model. Analysis of the human data
suggests that color is an additional channel of
perceptual information that leads to higher
categorization results at the expense of increased
reaction times in the intact condition. However, it
does not affect reaction times when only local
information is present. When color is removed, the
employed computational model follows the relative
performance decrease of human observers for each scene
category and can thus be seen as a perceptually
plausible model for human scene categorization based on
local image information.",

performed on these images involve a form of visual
search. Often, it is simply assumed that features can
be judged independently of each other in such tasks.
However, there is evidence for perceptual dependencies
when simultaneously presenting multiple features. Such
dependencies could potentially affect information
visualizations that contain combinations of features
for encoding information and, thereby, bias subjects
into unequally weighting the relevance of different
data dimensions. We experimentally assess (1) the
presence of judgment dependencies in a visualization
task (searching for a target node in a node-link
diagram) and (2) how feature contrast relates to
salience. From a visualization point of view, our most
relevant findings are that (a) to equalize saliency
(and thus bottom-up weighting) of size and color, color
contrasts have to become very low. Moreover,
orientation is less suitable for representing
information that consists of a large range of data
values, because it does not show a clear relationship
between contrast and salience; (b) color and size are
features that can be used independently to represent
information, at least as far as the range of colors
that were used in our study are concerned; (c) the
concept of (static) feature salience hierarchies is
wrong; how salient a feature is compared to another is
not fixed, but a function of feature contrasts; (d)
final decisions appear to be as good an indicator of
perceptual performance as indicators based on measures
obtained from individual fixations. Eye tracking,

short of what the human visual system is capable of
resolving. Therefore, we undertook a graph
comprehension study using a very high resolution
stereoscopic display. In our first experiment, we
examined the effect of stereoscopic display, kinetic
depth, and using 3D tubes versus lines to display the
links. The results showed a much greater benefit for 3D
viewing than previous studies. For example, with both
motion and stereoscopic depth cues, unskilled observers
could see paths between nodes in 333 node graphs with
less than a 10\% error rate. Skilled
observers could see up to a 1000-node graph with less
than a 10\% error rate. This represented an
order of magnitude increase over 2D display. In our
second experiment, we varied both nodes and links to
understand the constraints on the number of links and
the size of graph that can be reliably traced. We found
the difference between number of links and number of
nodes to best account for error rates and suggest that
this is evidence for a ``perceptual phase transition.''

problem is even more involved. The purpose of this
paper is to present a study based on eye tracking for
investigating the perception of visual realism of
static images with different visual qualities. The
eye-fixation clusters helped to define salient image
features corresponding to 3D surface details and light

This enabled the definition and categorization of image
attributes affecting the perception of photorealism.
The dynamics of the visual behavior of different

movements. We also demonstrated how the different image
categories used in the experiments were perceived with
varying degrees of visual realism. The results
presented can be used as a basis for investigating the
impact of individual image features on the perception
of visual realism. This study suggests that post-recall

performed best overall. Further, heuristic prediction
power differed more between games than between

abstract = "Humans have the ability to identify objects under
varying lighting conditions with extraordinary
accuracy. We investigated the behavioral aspects of
this ability and compared it to the performance of the
illumination cones (IC) model of Belhumeur and Kriegman
[1998]. In five experiments, observers learned 10 faces
under a small subset of illumination directions. We
then tested observers' recognition ability under
different illuminations. Across all experiments,
recognition performance was found to be dependent on
the distance between the trained and tested
illumination directions. This effect was modulated by
the nature of the trained illumination directions.
Generalizations from frontal illuminations were
different than generalizations from extreme
illuminations. Similarly, the IC model was also
sensitive to whether the trained images were
near-frontal or extreme. Thus, we find that the nature
of the images in the training set affects the accuracy
of an object's representation under variable lighting
for both humans and the model. Beyond this general
correspondence, the microstructure of the
generalization patterns for both humans and the IC
model were remarkably similar, suggesting that the two
systems may employ related algorithms.",

approach to face-image analysis based on identifying
distinctive areas of each individual's face by its
comparison to others in the population. The method
differs from most others---that we refer as unary
---where salient regions are defined by analyzing only
images of the same individual. We extract a set of
multiscale patches from each face image before
projecting them into a common feature space. The degree
of ``distinctiveness'' of any patch depends on its
distance in feature space from patches mapped from
other individuals. First a pairwise analysis is
developed and then a simple generalization to the
multiple-face case is proposed. A perceptual
experiment, involving 45 observers, indicates the
method to be fairly compatible with how humans mark
faces as distinct. A quantitative example of face
authentication is also performed in order to show the
essential role played by the distinctive information. A
comparative analysis shows that performance of our
n-ary approach is as good as several contemporary
unary, or binary, methods, while tapping a
complementary source of information. Furthermore, we
show it can also provide a useful degree of

we propose a tone-mapping operator (TMO) to compress
the luminance dynamic range while preserving the
driver's performance for a visual task relevant for a
driving situation. We address three display issues of
some consequences for road image display: luminance
dynamics, image quantization, and high minimum
displayable luminance. Our TMO characterizes the
effects of local adaptation with a bandpass
decomposition of the image using a Laplacian pyramid,
and processes the levels separately in order to mimic
the human visual system. The contrast perception model
uses the visibility level, a usual index in road
visibility engineering applications. To assess our
algorithm, a psychophysical experiment devoted to a
target detection task was designed. Using a Landolt
ring, the visual performances of 30 observers were
measured: they stared first at a high-dynamic range
image and then at the same image processed by a TMO and
displayed on a low-dynamic range monitor, for
comparison. The evaluation was completed with a visual
appearance evaluation. Our operator gives good
performances for three typical road situations (one in
daylight and two at night), after comparison with four
standard TMOs from the literature. The psychovisual

describe another technique (called Size technique) to
enhance the speed technique and simulate texture
sensations by varying the size of the cursor according
to the local height of the texture displayed on the
computer screen. With the size technique, the user
would see an increase (decrease) in cursor size
corresponding to a positive (negative) slope of the
texture. We have conducted a series of experiments to
study and compare the use of both the size and speed
technique for simulating simple shapes like bumps and
holes. In Experiment 1, our results showed that
participants could successfully identify bumps and
holes using the size technique alone. Performances
obtained with the size technique reached a similar
level of accuracy as found previously with the speed
technique alone. In Experiment 2, we determined a point
of subjective equality between bumps simulated by each
technique separately, which suggests that the two
techniques provide information that can be perceptually
equivalent. In Experiment 3, using paradoxical
situations of conflict between the two techniques, we
have found that participants' answers were more
influenced by the size technique, suggesting a
dominance of the size over the speed technique.
Furthermore, we have found a mutual reinforcement of
the techniques, i.e., when the two techniques were
consistently combined, the participants were more
efficient in identifying the simulated shapes. In
Experiment 4, we further observed the complex
interactions between the information associated with
the two techniques in the perception and in the
decision process related to the accurate identification
of bumps and holes. Taken together, our results promote
the use of both techniques for the low-cost simulation

a greedy approach to estimate the order in which

a very coarse approximation. We perform a user study to
validate its behaviour, as well as investigate the
impact of the choice of image fidelity metric as well
as that of user parameters. The three metrics
considered fall in the physical, statistical and
perceptual categories. The overall benefit of our
method is the semiautomation of the view selection
process, resulting in unstructured lumigraphs that are
thriftier in texture memory use and faster to render.
Using the same framework, we adjust the parameters of

motion affects the perceived sex of both androgynous

use of neutral walks is better than creating ambiguity
by assigning an incongruent motion. In Experiment 2 we
investigated further the influence of body shape and
motion on realistic male and female models and found

shapes influenced sex perception. Also, that
exaggerated female body shapes influences sex

However few algorithms exploit the human visual system

attributes could be quite relevant for this task.
Particularly, the {\em masking effect\/} defines the
fact that one visual pattern can hide the visibility of
another. In this context we introduce an algorithm for

local measure of geometric noise on the surface.
Indeed, a textured (or {\em rough\/}) region is able to
hide geometric distortions much better than a smooth
one. Our measure is based on curvature analysis on
local windows of the mesh and is independent of the
resolution/connectivity of the object. The accuracy and
the robustness of our measure, together with its
relevance regarding visual masking have been

abstract = "While rotating visual and auditory stimuli have long
been known to elicit self-motion illusions (``circular
vection''), audiovisual interactions have hardly been
investigated. Here, two experiments investigated
whether visually induced circular vection can be
enhanced by concurrently rotating auditory cues that
match visual landmarks (e.g., a fountain sound).
Participants sat behind a curved projection screen
displaying rotating panoramic renderings of a market
place. Apart from a no-sound condition, headphone-based
auditory stimuli consisted of mono sound, ambient
sound, or low-/high-spatial resolution auralizations
using generic head-related transfer functions (HRTFs).
While merely adding nonrotating (mono or ambient) sound
showed no effects, moving sound stimuli facilitated
both vection and presence in the virtual environment.
This spatialization benefit was maximal for a medium
($20^\circ \times 15^\circ$) FOV, reduced for a larger
($54^\circ \times 45^\circ$) FOV and unexpectedly absent
for the smallest ($10^\circ \times 7.5^\circ$) FOV.
Increasing auralization spatial fidelity (from low,
comparable to five-channel home theatre systems, to
high, 5^\circ resolution) provided no further benefit,
suggesting a ceiling effect. In conclusion, both
self-motion perception and presence can benefit from
adding moving auditory stimuli. This has important
implications both for multimodal cue integration
theories and the applied challenge of building
affordable yet effective motion simulators.",

distances accurately in full-cue, real-world
environments using visually directed actions. However,
in virtual environments viewed with head-mounted

act as though the virtual space is smaller than
intended. This is a surprising result given how well
people act in real environments. The behavior in the
virtual setting may be linked to distortions in the
available visual cues or to a person's ability to
locomote without vision. Either could result from
issues related to added mass, moments of inertia, and
restricted field of view in HMDs. This article
describes an experiment in which distance judgments
based on normal real-world and HMD viewing are compared
with judgments based on real-world viewing while
wearing two specialized devices. One is a mock HMD,
which replicated the mass, moments of inertia, and
field of view of the HMD and the other an inertial
headband designed to replicate the mass and moments of
inertia of the HMD, but constructed to not restrict the
field of view of the observer or otherwise feel like
wearing a helmet. Distance judgments using the mock HMD
showed a statistically significant underestimation
relative to the no restriction condition but not of a

Somewhat analogous to dark adaptation, reduction of
peripheral color tends to simulate scotopic viewing
conditions. This holds significant implications for
chromatic Level Of Detail management. Specifically,
while peripheral spatiotemporal detail can be
attenuated without affecting visual search, often
dramatically (e.g., spatial detail can be so reduced up

reduction is likely to be noticed much sooner.
Therefore, color LOD reduction (e.g., via compression),

marker of cognitive load, we can design Web pages which
are easier to interact with. We have devised an initial
empirical experiment, using card sorting and triadic
elicitation, to test our theories and assumptions, and
have built an initial baseline sequence of 20 Web pages
along with a library of qualitative and anecdotal
feedback. Using this library, we define visual
complexity, ergo perceived interaction complexity, and
by taking these pages as ``prototypes'' and ranking
them into a sequence of complexity, we are able to
group them into: simple, neutral, and complex. This

abstract = "Visual perception is an inherently selective process.
To understand when and why a particular region of a
scene is selected, it is imperative to observe and
describe the eye movements of individuals as they go
about performing specific tasks. In this sense, vision
is an active process that integrates scene properties
with specific, goal-oriented oculomotor behavior. This
study is an investigation of how task influences the
visual selection of stimuli from a scene. Four eye
tracking experiments were designed and conducted to
determine how everyday tasks affect oculomotor
behavior. A portable eyetracker was created for the
specific purpose of bringing the experiments out of the
laboratory and into the real world, where natural
behavior is most likely to occur. The experiments
provide evidence that the human visual system is not a
passive collector of salient environmental stimuli,
nor is vision general-purpose. Rather, vision is active
and specific, tightly coupled to the requirements of a
task and a plan of action. The experiments support the
hypothesis that the purpose of selective attention is
to maximize task efficiency by fixating relevant
objects in the scene. A computational model of visual
attention is presented that imposes a high-level
constraint on the bottom-up salient properties of a
scene for the purpose of locating regions that are
likely to correspond to foreground objects rather than
background or other salient nonobject stimuli. In
addition to improving the correlation to human subject
fixation densities over a strictly bottom-up model
[Itti et al. 1998; Parkhurst et al. 2002], this model
predicts a central fixation tendency when that tendency
is warranted, and not as an artificially primed
location bias.",

showing where a subject is looking, the subject's
Point-of-Regard (POR), for each frame of a video of the
scene. This information can be extremely valuable, but
its analysis can be overwhelming. Analysis of
eye-tracked data from portable (wearable) eye trackers
is especially daunting, as the scene video may be
constantly changing, rendering automatic analysis more
difficult. A common way to begin analysis of POR data
is to group these data into fixations. In a previous
article, we compared the fixations identified (i.e.,
start and end marked) automatically by an algorithm to
those identified manually by users (i.e., manual
coders). Here, we extend this automatic identification
of fixations to tagging each fixation to a
Region-of-Interest (ROI). Our fixation tagging
algorithm, FixTag, requires the relative 3D positions
of the vertices of ROIs and calibration of the scene
camera. Fixation tagging is performed by first
calculating the camera projection matrices for
keyframes of the scene video (captured by the eye
tracker) via an iterative structure and motion recovery
algorithm. These matrices are then used to project 3D
ROI vertices into the keyframes. A POR for each
fixation is matched to a point in the closest keyframe,
which is then checked against the 2D projected ROI
vertices for tagging. Our fixation tags were compared
to those produced by three manual coders tagging the
automatically identified fixations for two different
scenarios. For each scenario, eight ROIs were defined
along with the 3D positions of eight calibration
points. Therefore, 17 tags were available for each
fixation: 8 for ROIs, 8 for calibration points, and 1
for ``other.'' For the first scenario, a subject was
tracked looking through products on four store shelves,
resulting in 182 automatically identified fixations.
Our automatic tagging algorithm produced tags that
matched those produced by at least one manual coder for
181 out of the 182 fixations (99.5\% agreement). For
the second scenario, a subject was tracked looking at
two posters on adjoining walls of a room. Our algorithm
matched at least one manual coder's tag for 169
fixations out of 172 automatically identified (98.3\%
agreement).",

that illumination directions can be down-sampled more

results from the experiment and revealed that subjects
were fixating at locations aligned with direction of
main gradient in rendered stimuli. As this gradient was
mostly aligned with illumination gradient, we conclude
that subjects were observing materials mainly in

abstract = "In this article we evaluate the use of approximate
visibility for efficient global illumination.
Traditionally, accurate visibility is used in light
transport. However, the indirect illumination we
perceive on a daily basis is rarely of high-frequency
nature, as the most significant aspect of light
transport in real-world scenes is diffuse, and thus
displays a smooth gradation. This raises the question
of whether accurate visibility is perceptually
necessary in this case. To answer this question, we
conduct a psychophysical study on the perceptual
influence of approximate visibility on indirect
illumination. This study reveals that accurate
visibility is not required and that certain
approximations may be introduced.",

abstract = "Panoramic images are very effective at conveying a
visual sense of presence at very low cost and great
ease of authoring. They are, however, limited in the
navigation options they offer, unlike 3D
representations. It is therefore desirable to provide
pleasing transitions from one panorama to another, or
from a panorama to a 3D model. We focus on motions
where the viewers move toward an area of interest, and
on the problem of dealing with occluders in their path.
We discuss existing transition approaches, with
emphasis on the additional information they require and
on the constraints they place on the authoring process.
We propose a compromise approach based on faking the
parallax effect with occluder mattes. We conduct a user
study to determine whether additional information does
in fact increase the visual appeal of transitions. We
observe that the creation of occluder mattes alone is
only justified if the fake parallax effect can be
synchronized with the camera motion (but not
necessarily consistent with it), and if viewpoint
discrepancies at occlusion boundaries are small. The
faster the transition, the less perceptual value there
is in creating mattes. Information on view alignment is
always useful, as a dissolve effect is always preferred
to fading to black and back.",

abstract = "Visual Difference Predictor (VDP) models have played a
key role in digital image applications such as the
development of image quality metrics. However, little
attention has been paid to their applicability to
peripheral vision. Central (i.e., foveal) vision is
extremely sensitive for the contrast detection of
simple stimuli such as sinusoidal gratings, but
peripheral vision is less sensitive. Furthermore,
crowding is a well-documented phenomenon whereby
differences in suprathreshold peripherally viewed
target objects (such as individual letters or patches
of sinusoidal grating) become more difficult to
discriminate when surrounded by other objects
(flankers). We examine three factors that might
influence the degree of crowding with natural-scene
stimuli (cropped from photographs of natural scenes):
(1) location in the visual field, (2) distance between
target and flankers, and (3) flanker-target similarity.
We ask how these factors affect crowding in a
suprathreshold discrimination experiment where
observers rate the perceived differences between two
sequentially presented target patches of natural
images. The targets might differ in the shape, size,
arrangement, or color of items in the scenes. Changes
in uncrowded peripheral targets are perceived to be
less than for the same changes viewed foveally.
Consistent with previous research on simple stimuli, we
find that crowding in the periphery (but not in the
fovea) reduces the magnitudes of perceived changes even
further, especially when the flankers are closer and
more similar to the target. We have tested VDP models
based on the response behavior of neurons in visual
cortex and the inhibitory interactions between them.
The models do not explain the lower ratings for
peripherally viewed changes even when the lower
peripheral contrast sensitivity was accounted for; nor
could they explain the effects of crowding, which
others have suggested might arise from errors in the
spatial localization of features in the peripheral
image. This suggests that conventional VDP models do
not port well to peripheral vision.",
