See full text

A method for encoding at least one image divided into blocks. The method implements, for a current block to be encoded: determining a first prediction type for the current block; determining a prediction procedure associated with the first prediction type; obtaining a predictor block on the basis of the determined prediction procedure; and calculating a residual block that represents the difference between the predictor block obtained and the current block. The method also includes: selecting a prediction procedure from among a plurality of prediction procedures of a second type, different from the first type; and encoding the residual block calculated by using an encoding parameter determined on the basis of the selected prediction procedure.
