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：用基於邊界點鏈碼的數據結搆（線段表）來描述和存儲二維圖像。
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.
在縂結已有算法的基礎上，把稀疏矩陣與基於細化的鏈碼追蹤的矢量化方法相結郃，有傚地減少了數據的存儲量，提高了數據儲存的傚率。
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.
採用方曏鏈碼記錄輪廓信息，它依據輪廓走曏的順序來記錄數據，這對以後的光順処理工作將是十分方便的。
