An Improved Image Smoothing Method Based on Rough Sets
改进的基于粗糙集的图像平滑

An improved image filtering on Rough Sets is proposed in the paper.The method regards the traditional selective masking smooth filtering method as the thinking foundation.According to looking for the mask a pixel belongs to,then the mask RS precision approximation is used to precede image pixel to smooth whole image.It not only realizes cleaning noise and keeping the boundary, but also increases the contrast of picture and makes vision distinction restored picture to original one be minimum.In another words,while denoising the method keeps good details,increases the contrast degree of the picture,and improves the picture quality than the traditional pre-processing method.
