Abstract and Keywords

One of the important roles of our visual system is to detect and segregate objects. Neurons in the early visual system extract local image features from the visual scene. To combine these features into separate, global objects, the visual system must perform some kind of grouping operation. One such operation is contour integration. Contours form the outlines of objects, and are the first step in shape perception. We discuss the mechanism of contour integration from psychophysical, neurophysiological, and computational perspectives.

Keywords: contours, global integration, grouping, shape perception, computations
