A Synthetic Filtering Method for Restoration of Images Contaminated by Mixed Noise
Chao Chen · Microprocessors · 2007
In this paper,a synthetic filtering denoising method based on LoG(Laplacian of Gaussian) method of edge detection is presented.At first,the median filter is applied to remove impulse noise,latter it detects the edge of image with LoG method of edge detection,and gets the edge image.Then the Wiener filter is employed further to remove Gaussian and additional noise,and gets the smoothing image.Finally,the edge image is embed into the smoothing image.The method can not only wipe off effectively the noise of images contaminated by mixed Gaussian and Impulse noise,but also can keep the edge information of images and improve the denoising effect and distinct of images.
