Abstract (en)
[origin: WO2015055937A1] The invention concerns the encoding of at least one image (ICj) divided into blocks, characterised in that it comprises, for a current block (Bu) to be encoded, the steps of: - determining (C3) a set of candidate predictive blocks (BP1 1; BP12,..., BP1 V,..., BP1 Q), - for at least one candidate predictive block (BP1 V) from said set: obtaining (C4) a residual bloc representative of the difference between the candidate predictive block and the current block (Bu), identifying (C10), in said set of candidate predictive blocks, a candidate predictive block, said identification being a function of said obtained current residual block, selecting (C12a)) said at least one candidate predictive block if it is equal to the identified predictive block, - determining (C13), from the candidate predictive blocks likely to have been selected at the end of the selection step, a candidate predictive block (BP1 opt), by means of a predefined criterion (J), - encoding (C15-C17) the residual block representative of the difference between the determined candidate predictive block and the current block (Bu).
