Abstract
A method of coding at least one image sliced into blocks. The method implements, for a current block to be coded of the image: predicting the current block in accordance with a prediction mode selected from among a plurality of predetermined prediction modes, calculating a residual data block representative of a difference between a predictor block obtained on completion of the prediction and the current block, applying a transform operation to the data of the residual block, the transform operation belonging to a set of transform operations previously stored in association with a selected prediction mode, and coding the data obtained from the transform operation. The number of transform operations contained in the set associated with the selected mode is different from the number of transform operations contained in a set of transform operations stored in association with at least one other predetermined prediction mode of the plurality.
