The present disclosure relates to the search of more than one K-integer best-matching blocks per block within an image, corresponding to best patches for subsequent filtering. In particular, the positions of K best-matching blocks for a template block are found within an image search area, by performing calculations of the similarity between the template block and a test block at all offset positions within a search area. The positions of K or more best-matching blocks for a non-template block are found within an image search area, by performing calculations of the similarity between the non-template block and a test block at all offset positions found as offsets of best-matching blocks for all template blocks.
An apparatus for filtering each of a plurality of blocks in an area of pixels within an image using, for each of the plurality of blocks, a respective plurality of best-matching blocks found in a search image region, the apparatus comprising processing circuitry configured to:
A method for filtering each of a plurality of blocks in an area of pixels or a super block within an image using, for each of the plurality of blocks, a respective plurality of best-matching blocks found in a search image region, the method comprising the steps of:
