In the Freeman chain code based on a new shape description coding: the direction of the smallest and statistical code. The method of image translation, rotation invariance with the advantages of scale transformation on the proportion of the characteristics of success. The shape of the corresponding matching algorithm : the direction of the smallest measure of entropy and statistics to describe the shape of the direction of code similarity. simulation test to verify that the effectiveness of shape retrieval methods and feasibility.
