This review briefly discusses processes that have been suggested in the last 25years as
important to the intermediate stages of visual processing of patterns. Five categories of …

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 …

Natural scenes contain a rich variety of contours that the visual system extracts to segregate
the retinal image into perceptually coherent regions. Covert spatial attention helps extract …

Segmenting scenes into distinct surfaces is a basic visual perception task, and luminance
differences between adjacent surfaces often provide an important segmentation cue …

Visual pattern detection and discrimination are essential first steps for scene analysis.
Numerous human psychophysical studies have modeled visual pattern detection and …

A fundamental task of the visual system is to extract figure–ground boundaries between
objects, which are often defined, not only by differences in luminance, but also by “second …

Luminance variations are ambiguous: they can signal changes in surface reflectance or
changes in illumination. Layer decomposition—the process of distinguishing between …

Recent work has shown that salient perceptual singularities occur in visual textures even in
the absence of feature gradients. In smoothly varying orientation-defined textures, these …

Foveal detection thresholds for luminance-modulated (LM) and contrast-modulated (CM)
blobs in the presence of fixed modulation, laterally placed noise blobs (separations of 0–6°) …
