Abstract :
In this paper, we proposed an improvement on the 3D shape descriptor that we presented in detail in [1]. The improvement made of this method is concerning the reduction of the computation time. Before extracting the vectors descriptors, the classification step of the images is necessary, we introduced at this stage the X-means method. The comparison results of our descriptor and the improved version show the superiority of the improvement method.
