<P>PROBLEM TO BE SOLVED: To provide a method for reconstructing a current block of N pixels. <P>SOLUTION: The method comprises : a step 100 for decoding and inverse quantization of N residue coefficients; a step 100 for determining N reference coefficients; steps 110, 120, 130, 140, 160, and 170 for repetitively reconstructing N coefficients for the current block from the N residue coefficients and N prediction coefficients determined from the N reference coefficients by taking account of an illumination variation model defined by at least one illumination variation parameter; and a step 180 for transforming the N reconstructed coefficients to a current block of N pixels. The illumination variation parameter is refined on each reconstruction of k coefficients for the current block with k being an integer and 1≤k≤N. <P>COPYRIGHT: (C)2013,JPO&INPIT |
