Abstract:This paper improved the establishment of 2D histogram to contain more detailed information of noise estimation, according to which the image was divided into noise sub-image and non-noise sub-image. Then mean shift was applied to cluster and segment. The modified Gaussian kernel function could smooth noise better and cluster more accurately in non-noise sub-image. The experimental results show that the improved algorithm has better performance of anti-noise and more accurate precision.......
