Abstract: A binary code of the compression algorithm is presented. The black and white run-lengths in the binary code stream are compressed halved, which could also be progressed by selecting different initial length according to the different length distribution. Numerical experiments show that the algorithm has a better compression efficiency compare with that of the traditional methods of run-length code, and has good application value.
Key words: lossless compression, Run Length Coding (RLC), Binary image compression, image encoding, bit-plane coding
摘要: 提出了一种新的二进制码流压缩算法。该算法针对二进制码流中的黑长、白长进行减半压缩处理,且可依据黑长与白长的分布特点,选取不同的初始长度开始进行减半压缩处理。数值实验表明,该算法在压缩效率上高于传统的游程编码(RLC)方法,具有较好的应用价值。
