… However, image rotation violates not only the constraints imposed by the gravitational
frame but also the global distribution of luminance contrast across orientations (amplitude …

… In this experiment we first estimated participants' luminance contrast threshold for
correctly categorizing scenes as highway or city, for both low- and high-pass SF filtered …

… The contrast and luminance was adjusted to specific values for each image: images of low
… on scene categorization (deep scene network). B) Receptive field (RF) of example deep …

… luminance-based cues was used to classify the novel stimuli. In conclusion, natural stimuli
can be used to probe ordinate-level categorization … based upon local luminance cues cannot …

… To investigate the effect of global changes in luminance contrast independently from other
… luminance contrast gradually in the horizontal direction ( Figure 1c). The luminance of the …

… scene categorization performance with and without contrast normalization. Participants see
images of scenes from six scene … Note that we did not attempt to linearize the luminance …

… The contrast (ie the difference in luminance values) is reduced in HSF relative to LSF …
contrast normalization induced change in retinotopic processing of SF during scene categorization…

… Moreover, in Study 3, we also found tightly-controlled stimuli of horizontal luminance gradient
to be behaviorally categorized as an “object” more often than a “place”. Together, these …

… luminance of 128 on a gray-level scale with a standard deviation of 25.5, in order to match
the mean luminance and RMS contrast of the filtered scenes … of the same scene presented for …

… The input of the model has to be an image in a graylevel format, since for the moment we
only focus on the luminance information, without taking into account the chrominance. Along …
