A rectifying transformation is required to sense variations in texture contrast. Various
theoretical and practical considerations have inclined researchers to suppose that this …

Humans can easily segregate texture regions based on differences in contrast, orientation,
and contrast polarity. It has been suggested that these abilities can be inclusively modeled …

We measured the just-noticeable difference (JND) in orientation variance between two
textures (Figure 1) as we varied the baseline (pedestal) variance present in both textures …

Recent investigations of texture and motion perception suggest two early filtering stages: an
initial stage of selective linear filtering followed by rectification and a second stage of linear …

Natural scenes contain localized variations in both first-order (luminance) and second-order
(contrast and texture) information. There is much evidence that first-and second-order stimuli …

We sought to determine whether the detection and the identification of texture modulations
are mediated by a common mechanism. On each trial two textures were presented, one of …

Two distinct paradigms have characterized most previous studies of texture perception: one
has dealt with texture segregation, the other with the processing of texture gradients …

Julesz [IRE Trans. Inf. Theory IT-8 (1962) 84] introduced the concept of statistically defined
textures and their perceptual discrimination. Julesz [Sci. Am. 232 (1975) 34] showed that …

For a patch of random visual texture embedded in a surrounding background of similar
texture, we demonstrate that the perceived contrast of the texture patch depends …

Many previous studies have examined the ease with which two spatially adjacent textures
can be segmented. Our goal is to examine the representational system that determines the …
