1. A decoding method comprising:
decoding a chroma block of a picture, said chroma block being intra predicted according to an intra linear prediction mode from a reconstructed co-located luma block reconstructed from at least two luma blocks;
determining a frontier inside the decoded chroma block by projecting lines of the reconstructed co-located luma block, said lines being co-located with the external frontiers of the at least two luma blocks; and
filtering along the frontier determined inside the decoded chroma block.
