The invention relates to a rapid mean filtering method for an image. At first, neighboring mean values of pixels f(2n, 2n) are calculated; next, the neighboring mean values of other pixels in a row or a column are obtained through the utilization of an intermediate result of the ...

This article presents a novel method for mean filtering that reduces the required number of additions and eliminates the need for division altogether. The time reduction is achieved using basic store-and-fetch operations and is irrespective of the image or neighbourhood size. This method has been ...
It consists of three major stages, these stages are bandwidth selection, mean shift filtering and mean shift segmentation. The proposed scheme is tested usingduodenumultrasound image, the experimental show the proposed scheme can produce accurate contours. Keyword:Medical ultrasound image; Mean shift ...
