摘要

A method for decoding a data stream representative of an image split into blocks. For a current block of the image, an item of information indicating a coding mode among a first and a second coding mode of the current block is decoded from the data stream and the current block is decoded depending on this information. When the coding mode of the current block corresponds to the second coding mode, the current block is reconstructed from a prediction obtained, for each pixel, from another previously decoded pixel belonging to the current block or to a previously decoded block of the image, and from a decoded residue associated with the pixel. At least one processing method is applied to the reconstructed current block for at least one pixel of the current block depending on the coding mode of the current block and/or the coding mode of the neighbouring blocks.

說明書

  • coding a prediction residue associated with said pixel obtained from the prediction of said pixel,
  • reconstructing said pixel from the decoded prediction residue associated with said pixel and the prediction of said pixel,
  • code the current block according to the coding mode indicated by the coded item of information,
  • when the coding mode of the current block corresponds to a coding mode distinct from the second coding mode, apply at least one processing method to the reconstructed current block,
  • when the coding mode of the current block corresponds to the second coding mode, disable the application of said at least one processing method to the reconstructed current block for at least one pixel of said current block.

    • According to a particular embodiment of the invention, such an encoding device is comprised in a terminal, or a server.

    The decoding method, respectively the encoding method, according to the invention can be implemented in various ways, notably in wired form or in software form. According to a particular embodiment of the invention, the decoding method, respectively the encoding method, is implemented by a computer program. The invention also relates to a computer program comprising instructions for implementing the decoding method or the encoding method according to any one of the particular embodiments previously described, when said program is executed by a processor. Such a program can use any programming language. It can be downloaded from a communication network and/or recorded on a computer-readable medium.
