Samsung patents image decoding method using transformed template matching
Samsung describes a method for decoding video images by comparing small sections of a picture, called templates, to find matching areas. The process involves applying a mathematical transformation to these templates before comparing them to improve accuracy. This helps the decoder reconstruct the image by finding the best matching reference block.
In the filing’s own words
A method for decoding an includes: determining a transformed template of the current block by performing transformation on a template of the current block; determining transformed templates of a plurality of candidate blocks by performing transformation on templates of the plurality of candidate blocks within a search area; comparing the transformed template of the current block with the transformed template of each of the plurality of candidate blocks; on the basis of the result of the comparison, determining a reference block of the current block from among the plurality of candidate blocks; generating a prediction block of the current block by using the reference block; and reconstructing the current block by using the prediction block of the current block.
What exactly they claim (claim 1)
1. A method of decoding an image, the method comprising: determining a transformed template of a current block by performing a transform on a template of the current block; determining transformed templates of a plurality of candidate blocks by performing a transform on templates of the plurality of candidate blocks in a search region; comparing the transformed template of the current block with each of the transformed templates of the plurality of candidate blocks; determining a reference block of the current block, from among the plurality of candidate blocks, based on results of the comparing; generating a prediction block of the current block using the reference block; and reconstructing the current block using the prediction block of the current block.
