Title: Method and apparatus for block-based image denoising

Abstract: A block-based image denoising method includes determining similarities between a current block and reference blocks within a search range around the current block, from among certain-sized blocks divided from an input image; determining weights of the reference blocks with respect to the current block based on the similarities; and generating resultant blocks by denoising the current block with respect to every block of the input image based on the weights of the reference blocks.
