Vectorial Computation of the Optical Flow in Color Image Sequences
Résumé
Actually in most applications, optical flow is computed from one luminance Y-plane and only a few methods refer to color optical flow. In fact, a brief analysis shows that these methods are either marginal approaches, whether dramatically time consuming techniques. Here, we propose a vectorial approach based upon a joint analysis of a structure tensor and a so called flow tensor, both computed from image derivatives
