An image enhancement method for noisy image

In this paper, image enhancement for noisy image has been studied. A simple approach to enhancement of noisy image data is presented. The proposed method is based on a two steps system that adopts pre-denosing step in order to prevent the noise increase during the sharpening of the image. The proposed method has better performance than available methods in the enhancement of noisy images. Simulation results show that this method can effectively improve the effect of sharpening the noisy image.
