lz77压缩算法单元源文件出自王咏刚先生的《笨笨数据压缩教程》中的lz77.c由崔东伟修改为pascal单元-lz77 compression algorithm module source file from Mr. Wang Yonggang' s " simple-minded, data compression tutorial" in lz77.c by Choi Dong-wei was revised to pascal unit

propose a novel joint data-hiding and compression scheme for digital images using side match vector quantization (SMVQ) and image inpainting. The two functions of data hiding and image compression can be integrated into one single module seam
