实验结果表明，这种方法大大提高了编码速度，而且能有效地压缩图像数据。

Experimental results indicate that images could be significantly compressed with our method, while encoding time is greatly reduced.

而小波变换多分辨率分解的优良特性，既能大幅度的压缩图像数据，又能很好的保留图像的绝大部分的信息。

The wavelet has the good multi-resolution decomposition features, which both have a significant compression of image data, but also retain most of the information of an image.
