It includes horizontal, vertical and diagonal-directions of 1D and 2D wavelet transform denoising process. It can reserve the directional edge of 1D wavelet transform denoising, and eliminate the blurred edge of 2D wavelet transform denoising.

• 该方法包括水平、垂直和对角线多个方向一维（1D）与二维（2D）两个小波变换消噪处理过程,汲取了1D方向数组小波变换消噪能较好保持方向性边沿的优点,消除了2D图像小波变换阈值法消噪造成的边沿模糊。
