Description: 在Freeman链码基础上,提出一种新的形状描述编码:最小和统计方向码. 该方法对图像平移、旋转具有不变性的优点,对尺度变换有成比例特点. 提出了相应的形状匹配算法:方向熵法度量最小和统计方向码描述的形状相似度. 仿真试验验证了这种形状检索方法的有效性与可行性.-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.
