摘要
给出了矩形点阵上八近邻图像的顶点链码(VCC)、Freeman链码和边界链码之间的转换算法,给出了图像边界的边界链码与顶点链码之间的相互转化算法和顶点链码与Freeman链码之间的相互转换算法,于是可以方便地直接由一种链码得到其他的链码表示,由某种链码获得的图像信息也为其他链码所共享.
This paper introduces the algorithm of the transformations among vertex chain code （abbreviation of VCC）, Freeman chain code and boundary chain code for 8-site neighborhood digital images. Thus if one kind of these chain codes has been obtained, it is easy to get other chain codes, and the image information obtained from some chain code can be shared by other chain codes.
