A method for coding a block of pixels is disclosed. The method comprises the following steps: determining, for each pixel of the current block, a prediction pixel by thresholding, with a current threshold value, of coefficients resulting from a transformation applied on a window covering at least the pixel of the current block and by inverse transformation applied to the thresholded coefficients, extracting from the current block a prediction block formed of prediction pixels to generate a residue block, and coding said residue block, According to the invention, the current threshold value is determined or coded from neighboring reconstructed pixels of the current block. |
