In natural scenes, two adjacent surfaces may differ in mean luminance without any sharp
change in luminance at their boundary, but rather due to different relative proportions of light …

In order to accurately parse the visual scene into distinct surfaces, it is essential to determine
whether a local luminance edge is caused by a boundary between two surfaces or a …

Visual texture is an important cue to figure-ground organization. While processing of texture
differences is a prerequisite for the use of this cue to extract figure-ground organization …

Previous studies have demonstrated that density is an important perceptual aspect of
textural appearance to which the visual system is highly attuned. Furthermore, it is known …

This review analyzes studies addressing second-order visual filters as a mechanism for
preattentive grouping of local visual information received from the outputs of striatal neurons …
