Abstract
Method and apparatus are provided for efficient reference data decoding for video compression by image content based search and ranking. An apparatus includes an entropy decoder for respectively entropy decoding an encoded respective rank number for each of a plurality of candidate reference blocks with respect to a current block to be decoded to obtain a decoded respective rank number there for. The encoded respective rank number is in place of and representative of respective reference data for each of the plurality of candidate reference blocks With respect to the current block. The apparatus further includes an inverse rank transformer for respectively transforming the decoded respective rank number for each of the plurality of candidate reference blocks with respect to the current block into the respective reference data there for based on a context feature of the current block with respect to the context feature of each of the plurality of candidate reference blocks.
