At present, binary image compression is still in the stage of lossless encoding with low compression ratios.

目前，二值图像压缩主要采用无损压缩方式，压缩倍数低。

The experiment results show that the new still image compression scheme provides higher perceptual quality and less encoding time than EZW, especially at low bit rates.

实验结果表明，该算法具有较好的图像复原质量和较快的编码速度，整体性能明显优于EZW方案（特别是低比特率下）。
