Method and device for encoding a block of an image and corresponding reconstructing method and device

摘要

The invention relates to image block encoding and decoding. More precisely, the invention relates to block prediction using reference blocks of the image. It is proposed a method which comprises using processing means for using at least the block for determining one reference block in an already encoded part of the image, encoding and reconstructing a part of the image, using at least the block for determining one reference block in the reconstructed part and a indicator referencing the one reference block, using the one reference block for determining at least one further reference block in the reconstructed part and encoding the determined indicator and a residual of the block with respect to a combination of the one and the at least one further reference block. Using the block for determination of the one reference block allows for selecting it such that it resembles the block and correlation with the block is maintained.
