Three experiments are reported concerning the texture density aftereffect. The experiments
address the question of how visual texture density information is encoded by examining …

The processing of texture patterns has been characterized by a model that first filters the
image to isolate one texture component, then applies a rectifying nonlinearity that converts …

Human texture vision has been modeled as a filter–rectify–filter (FRF) process, in which '2nd-
order'filters detect changes in the rectified outputs of luminance-based '1st-order'filters. This …

This work studies the preattentive discrimination of achromatic textures composed of
mixtures of different (Weber) contrasts. These textures differ not at all in local spatial …

We present a series of experiments in texture discrimination with textures whose local
elements are defined by their color (red and/or green), luminance polarity, and orientation …

The masking procedure by Paradiso and Nakayama (1991)(Vision Research, 31,(1221–
1236) was used to investigate brightness filling-in within textures made of line elements: a …

Thevisual system can use a rich variety of contours to segment visual scenes into distinct
perceptually coherent regions. However, successfully segmenting an image is a …

We present a model of human preattentive texture perception. This model consists of three
stages:(1) convolution of the image with a bank of even-symmetric linear filters followed by …

Recent experiments indicate that the segregation of visual structures (“texture
discrimination”) depends not only on the form of texture elements but also on their spacing …

The ability of the visual system to detect stimuli that vary along dimensions other than
luminance or color—“second-order” stimuli—has been of considerable interest in recent …
