摘要：
A method for decoding a picture divided into blocks is disclosed. The method comprises at least one iteration of:
a) determining (S20) for at least two blocks adjacent to a reconstructed part of the picture a priority level responsive at least to directional gradients computed in a causal neighborhood of said block; and
b) decoding (S22) a part of the picture comprising the block whose priority level is the highest.
