From primary edges to contours: modelling contour integration in human early vision.

According to the experimental observations, contour integration should occur in the primary visual area (V1). We propose a computational model of contour perception in human visual cortex using a recurrent neural network. Our approach is based on the neuro-physiological findings about the columns of ocular dominance and orientation in V1, and on some other existing mathematical models. We also developed a computer application for implementing and testing the proposed model.
