Jinping Song · Shuxue de shijian yu renshi · 2007
This article in the foundation of local extreme value detection and iterative median filter,Based on the picture structure and impulse noise characteristic analysis,Combines local extreme value detection and scope difference threshold value or the gradient difference threshold value detection method,Advance a iterative denoising algorithm based on noisy detection.And through the simulation experiment and the algorithm appraise,Confirmed the algorithm not only to be able to achieve very good denoising result,but also obtain the certain effect in the preserving picture detail information aspect.
