该算法针对噪声图像上每一点，应用自适应加权算子，对于不同的图像区域，算子自适应地进行窗口大小和输出像素值的改变。
The adaptive weighting operator is applied to the every point on the noised image, at the same time, it's window size and the corresponding output pixel value adaptively vary with the image area.
对矩形和圆形区域中各像素进行亚像素划分，确定各亚像素的权值，得到基于亚像素的综合加权区域能量。
Dividing pixels in rectangular and circular regions into subpixels and determining weight of each subpixel the composite weighted region energy of each pixel is obtained in the region.
