The human perceptual system has an astonishing capacity of combining a minimal amount of visual signals effectively into complex representations of form and qualia. This talk will discuss the contribution of visual signals of color and luminance contrast, and their interaction with geometric stimulus properties, to the perception of figure and ground in image representations. Implications for the cognitive assessment of what is likely to be nearer or further away from the observer in the real world will be made clear. Psychophysical data and perceptual effects, some of which are intuitively exploited by graphic artists, photographers and painters, will be shown and discussed. Some, but not all of them, can be explained in terms of interactions between hierarchically organized neural structures with distinct processing characteristics.
