An efficient image noise removal and enhancement method

This paper presents a new method to remove noise and enhance the image with the help of partial unsharp masking and conservative smoothing. In this method, unsharp masking is applied in partial way for detection of the edges and boundary lines in the image and then a conservative smoothing operation is applied on the selected areas to remove undesirable edges which represents the salt and pepper noise. Finally, the noise free edge image is added with the smoothed image to get the original image with reduced noise. The proposed method is compared with that of performance of mean and median filtering. The experimental results on synthetic and real images show the effectiveness of the proposed method.
