METHOD, SYSTEM AND DEVICE FOR IMAGE AND VIDEO CODING

摘要

A method of image processing or coding comprises dividing image data into a plurality of blocks of image data wherein each block is defined by a first positional index and a second positional index. For each block of image data, firstly the block of image data is processed at step 402 to generate at least one parameter value required to process one or more adjacent blocks of image data, secondly a position of a memory element in a parameter memory is determined by combining the first positional index of the block of image data with the second positional index of the block of image data, and thirdly the generated at least one parameter value is stored at step 406 in a memory element in the position by overwriting at least one parameter value generated from a previously processed block of image data which has been previously stored at the determined position in the parameter memory. The method enables at least one parameter value for an image section image section to be generated and stored in a position which is occupied by a previously generated parameter value. All of the parameter values are stored in a simple one-dimensional array which is computationally efficient to access.
