自适应六边形窗口加权均值滤波
Adaptive hexagonal window weighted mean filter
摘要
Abstract
The weighted average filtering algorithm has good filtering effect to the image polluted by the salt-and-pep-per noise, but there is a number of factors that influence the effect of this algorithm, for example choosing different filtering window has greater difference on the effect of filter. In this paper, there is a kind of adaptive hexagon window whose pixels in a horizontal direction are more than vertical direction, so the impact is different on the horizontal and vertical direction in the filtering process. The experimental results show that the filtering effect is better than general window to the image that has stronger pixel correlation on the level direction(or vertical direction).关键词
