A Method of Contour Matching Based on Chain Code
Huaiwei Lu · Computing Technology and Automation · 2007
In this paper,a boundary chain-code tracing method is used to extract the contour information,the process of thinning,de-noising,and encoding for contour are realized at one time,so a 1D string represented the 2D contour shape information is obtained,then a contour matching method based on chain-code is presented.The 2D fragments matching task is reduced into a 1D string matching problem so that the 2D fragments reassembling is simple.Experimental results show that the proposed method is efficient and accurate.
