The perception of shape is independent of the size and position of the shape and also of the visual cue that defines it. The same shape can be recognized whether defined by a difference in luminance, by motion, or by texture. Experiments showed that the shape selectivity of individual cells in the macaque inferior temporal cortex did not vary with the size and position of a shape and also did not vary with the visual cue used to define the shape. This cue invariance was true for static luminance and texture cues as well as for relative motion cues--that is, for cues that are processed in ventral and dorsal visual pathways. The properties of these inferior temporal cells meet the demands of cue-invariant shape coding.
