METHODS OF ENCODING AND RECONSTRUCTING IMAGE DATA AND DEVICES IMPLEMENTING SAID METHODS

摘要

The invention relates to a method for coding a block of N image data with N a positive integer comprising the step of : - transforming (S2) the block of N image data into a block of N transformed data; - quantizing (S4) the block of N transformed data into a block of N quantized data; - sampling (S6) the block of N quantized data into M sampled data according to a predefined sampling pattern, with M
