基于阈值判断的自适应中值滤波算法
An improved adaptive median filter based on noises detection
摘要
Abstract
The standard median filter can not do well both in noise suppression and detail preservation, an improved adaptive median filter based on threshold detection was proposed. The algorithm took full advantage of the relationship between the center pixel and its neighbor pixels' gray value, and it set a threshold based on the difference between the center pixel and its neighbor pixels when detecting the corrupted pixels. Experiment results show that the new algorithm can distinguish the pixel corrupted or not, and it is both effective in noises suppression and detail preservation.关键词
