A contour-based method--improved Freeman chain coding is discussed. We compare code length,chain length,rolling operation,and whole chain bits with the traditional coding,and provide the results of comparison analysis.

- 通過(guò)對MPEG-4的研究探討;提出一種基于邊緣輪廓的形狀編碼方法:改進(jìn)的Freeman鏈碼法;將它與傳統的鏈碼方法從碼長(cháng)、鏈碼長(cháng)度、是否獨立于旋轉操作、鏈碼總位數四個(gè)方面進(jìn)行了比較;給出比較分析結果.
