chain data code

基本解释

Material and Method: In this paper, we try to describe and store the image using a data structure, interval list, which was based on the Freeman Chain Code of the image′s boundary.
材料和方法：用基于边界点链码的数据结构（线段表）来描述和存储二维图像。
Based on the original thinning arithmetic, combine sparse matrix with vectorization of chain code traced, the storage of data is decreased and the efficiency of storage is improved.
在总结已有算法的基础上，把稀疏矩阵与基于细化的链码追踪的矢量化方法相结合，有效地减少了数据的存储量，提高了数据储存的效率。
The directional chain code is used to record the contour information data according to the trend of the contour, and this will be very convenient for the smoothing process later on.
采用方向链码记录轮廓信息，它依据轮廓走向的顺序来记录数据，这对以后的光顺处理工作将是十分方便的。
