In order to solve the problem that the traditional image smoothing method has caused the loss of information on the edge of the image, this paper proposes a classification smoothing filtering algorithm based on edge information. This algorithm detects the image egde, then uses different method to smooth the image edge pixels and the other pixels respectively, effectively eliminates noise while preserving the edge information. Experimental results shows, to reduce Gaussian noise and salt and pepper noise, our method takes less time, has good noise reduction effect, and keeps the image edge clear. So our method has a good practicality.
