A chromatic contour detector based on abrupt change techniques

A method for segmenting colored images based on contour detection is described. It involves the use of techniques based on abrupt change detection used in signal processing and control systems. This work is based on a theoretical framework: differential geometry, tensors, Neyman-Pearson's optimal decision. Good results are obtained with Gaussian and exponential noises. This method also provides a very good location of contours.
