摘要：

We propose the use of co-occurrence matrices/histograms (of relative distance, relative angle) between pairs of orientation tokens for silhouette recognition and texture discrimination. The orientation tokens are defined as the tangent vectors to the boundary of the silhouette, or the gradient vectors for grey images. The efficiency of the method is demonstrated with the help of three different series of experiments with real data. (C) 1998 Elsevier Science B.V. All rights reserved.
