Effective and Non-iterative Removal Based on the Median Filter for Salt-Pepper Noise from Images
Xiangchu Feng · Modern Electronics Technique · 2008
Salt-pepper impulsive noise removal is an important problem in image processing.The common median filter can get off majority of noise and thus destroys fine details.To some extent a variation of the peak-valley filter based on a recursive minimum-maximum method addressed this drawback,but the result is not enough.In this work,we consider the similarities between the center pixel and some of its neighbor pixels in search of corrupted pixels based on the above method.The experiment demonstrated the effectivity of the new method in both PSNR and destroyness of noise to original image.
