METHOD AND APPARATUS FOR ENHANCING DETAIL BASED ON NOISE ELIMINATION, AND METHOD AND APPARATUS FOR CALCULATING NOISE WEIGHT

摘要

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