摘要：Image smoothing is a key technology of image enhancement, which can remove noise in images. So, it is a necessary functional module in various image-processing software. Excellent smoothing algorithm can both remove various noises and preserve details. This paper analyzed some image smoothing algorithms. These algorithms have the ability of preserving details, such as gradient weighting filtering, self-adaptive median filtering, robust smoothing and edge preserving filtering. A robust smoothing algorithm is presented by combining non-linear and linear filtering according to the respective adaptation to different noises. Tests on images corrupted with various noises show that the new algorithm can both deal with corrupted images robustly and preserve details well
