高效率的变字长颜色编码与解码技术

提出了一种新的mB/nB(m＜n)变字长颜色编码技术,用颜色位同时作为字节头、标识位及校验位,提高了信息容量.mB位二进制串中0和的1个数差值大于2,字长映射为nB位,否则字长保持mB位,减少冗余码.随后提出了基于算术平均法的解码规则.理论分析及实测表明,该编码技术编码效率高达94％,比传统方法编码效率提高88％以上,具有很高的实用价值.

High-efficiency Variable-length Color Coding and Decoding Technology

The mB/nB(m＜n) variable-length color coding (VLCC) technology is proposed in this paper.The color bits are used as the header,identifier and check bits at the same time.The difference between 0 and 1 in the original binary string is greater than 2,and the length of binary string is remapped from mB bits to nB bits,otherwise the length remains mB bits.New decoding rules and properties are discussed for the VLCC.The experiment results show that the VLCC coding efficiency is up to 94 ％,which is more than 88 ％ higher than the traditional methods and has high practical value.
