无损链码技术的分析与比较
Analysis and comparison of research on lossless chain codes
【摘要】 为了给链码的进一步研究与应用提供建设性意见和参考,文中从两个方面介绍了无损链码技术,一是基于像素的链码技术,主要介绍弗尔曼(Freeman)链码技术;二是基于边界的链码技术,主要介绍顶点链码技术。介绍了6种典型的Freeman链码和6种典型的顶点链码,对各链码的产生、主要思想及特性进行了详细的论述,给出了各链码的综合比较与评价,为链码的应用者与研究者提供便利。
【Abstract】 To provide both constructive suggestions and references for further research and application on chain codes,techniques of lossless chain codes are introduced from two aspects.One is pixel-based techniques of chain codes,which mainly refers to the techniques of Freeman chain codes.The other is edge-based techniques of chain codes,which mainly refers to the techniques of vertex chain codes.The techniques of Freeman chain codes are introduced by six representative Freeman chain codes and six representative vertex chain codes.The generation,main ideas and properties of all the mentioned chain codes are described in detail.In the end,to provide conveniences for chain code appliers and researchers,the general comparsion and evaluation among them are provided.
【Key words】 lossless chain code; Freeman chain code; vertex chain code; compare; evaluation;
