Abstract

Special issue on perceptual transparency Perceptual transparency occurs when two (or more) overlapping patterns are seen at different depth levels, so that one pattern appears. to be seen through another. In recent years there has been an increased interest in the study of perceptual transpar- ency. This interest is motivated, in part, by the fact that the explanation of perceptual transparency challenges current computational, psychological, and neurophysio- logical theories which deal with the extraction and processing of low-level visual information. From a computational point of view, most current theories can only deal with single valued visual attributes at each image location. Perceptual transparency, on the other hand, seems to require multiple values at the same location. From a psycho- logical point of view the perception of transparency depends on how visual attributes, like edge continuity or luminance, are locally related, and how perceptual rules for pattern grouping and segmentation are globally satisfied over the image. Perception of transparency can alter the depth relations between objects, as well as the perceived values of object attributes, including luminance, color, and shape. From a neurophy- siological point of view perceptual transparency requires the understanding of how populations of cells, which are
