| 摘 要： | 介绍一种新的第二代小波变换——红-黑小波变换，它是把矩形栅格的数字图像分成红块和黑块，利用二雏提升格式进行构造。并从理论上与张量积小波变换进行了比较。实验表明红．黑小波变换可以更有效地去除图像的相关性并得到更稀疏的图像表示，在图像压缩中红．黑小波变换比传统小波变换更有效。

| Abstract: | In this paper, a new kind of the second-generation wavelet transform on a rectangular grid is presented, which is based on a red-black blocking scheme.Comparing with classical tensor product wavelets in theory,the experiments show that the relativity of image can mostly be eliminated and the sparser representation of image can be obtained by the Red-Black wavelet transform. it is more effective in image compression by the Red-Black wavelet transform. |
