- W2372358071 abstract "Natural images are prone to exist a variety of noises. The object of image filter is to remove noises as well as save details simultaneously. And it is easy to make image become fuzzy by using usual averaging filter, the effect of averaging filter is not ideal. Although it has good effect by using median filter, it is easy to make image become mistiness and lose detail information. In allusion to this question, in this paper, we proposed a method of image filter based on direction gradient. This new method selects a 3×3 neighborhood, constructs 4 templets of orientation gradient, and processes noises, edge and inside pixel of image according to the magnitude of 4 templets of orientation gradient. The result of experiment proves that the new method not only saves the original image information and has a good Signal-to-Noise Ratio, but also removes noises simultaneously." @default.
