In order to improve compression ratio, the combination of lossy and lossless coding method is used in video coding systems.
为了提高压缩率，视频编码技术中一般会采用有损和无损压缩编码相结合的方式。
IWT achieves great success in the lossless coding and compression, but its efficiency in the loss compression is far lower than the traditional DWT.
IWT在无损编码与压缩中获得了很大成功，但在有损压缩效率上远低于传统的DWT。
Experimental results of this algorithm indicate lossless coding rates better than those achieved by BWT-based compression algorithms using integer codes.
该算法的实验结果表明其压缩比率要优于采用整数码的BWT类压缩算法。
