Abstract

Combined with the Huffman encoding theory, the code 2 with highest emergence-probability and continution-frequency is indicated by a binary number 0,the combination of 1 and 3 with higher emergence-probability and continutionfrequency are indicated by two binary number 10,and the corresponding frequency-code are attached to the two kinds of code,the length of the frequency-code can be assigned beforehand or adaptive automatically,the code 1 and 3 with lowest emergence-probability and continution-frequency are indicated by the binary number 110 and 111 respectively.The relative encoding efficiency and decoding efficiency are supplemented to the current performance evaluation system of the chain code.the new chain code is compared with a current chain code through the test system progamed by VC++, the results show that the basic performances of the new chain code are significantly improved, and the performance advantages are improved with the size increase of the graphics.
