Shape Perception: Complex Contour Representation in Visual Area V4
A recent study has put forward a physiologically plausible population model that implements a parts-based shape-coding scheme for macaque visual area V4.
متن کاملInvestigating Shape Representation in Area V4 with HMAX
Motivation: Based on the known properties of the neurons in the earlier information-processing areas, such as V1, it is possible to make a very quantitative model of how the visual cortex may be organized. In fact, Riesenhuber and Poggio’s HMAX model has been useful in making several physiologically consistent predictions about the properties of the visual cortex [4]. The HMAX model can also be...
متن کاملVisual representation of contour and shape
Contours provide an essential source of information about shape and, along contours, points with the greatest magnitude of curvature tend to be most informative. This concentration of information is closely tied to internal generative models of contours employed by the visual system. In going from open to closed contours, the sign of curvature becomes perceptually significant, with negative-cur...
متن کاملTemporal dynamics of 2D and 3D shape representation in macaque visual area V4.
We studied the temporal dynamics of shape representation in area V4 of the alert macaque monkey. Analyses were based on two large stimulus sets, one equivalent to the 2D shape stimuli used in a previous study of V2, and the other a set of stereoscopic 3D shape stimuli. As in V2, we found that information conveyed by individual V4 neurons about the stimuli tended to be maximal during the initial...
