摘要：A method to enhance detail of an image based on noise elimination includescalculating a noise weight corresponding to a probability that a center pixel, located in ablock of pixels of a region of the image, is noise by using a difference between the centerpixel and a surrounding pixel located in the block of pixels, calculating a first substitutionvalue for the center pixel based on the noise weight; and calculating a secondsubstitution value for the center pixel by using the noise weight and a sharpen filter.
