本文提出一种基于图像分辨率的自适应分层式图像平滑算法。首先对每个像素在不同分辨率窗口下平滑处理，然后找出该像素被判断为同质区域下的最大窗口，在此，判断方法为比较其同质度和全局鲁棒估计方差的大小。在平滑处理过程中，对同质区域和纹理域分别采用不同算法处理。-This paper presents an adaptive hierarchical image resolution image smoothing algorithm. First, for each pixel smoothing window at different resolutions, and then find the pixel is judged to be the largest homogeneous area under the window, where, judging by comparing their degree of homogeneity and the size of the global robust variance estimation. In the smoothing process, homogeneous regions and textures using different domain algorithm processing.
