A method for encoding and decoding a digital image signal, and associated devices. A method for encoding a digital image signal represented by a set of digital samples includes applying a segmentor to a reference digital image signal to obtain subsets of digital samples and applying a same filter among a set of predetermined filters to each sample of a subset of digital samples. The method includes a step of selecting (S320) a subset of segmentors from a predetermined set of segmentors based upon at least one characteristic obtained from the reference digital image signal, and a step (S330) of determining one segmentor among the selected subset of segmentors to apply to the reference digital image signal. Advantageously, a large initial set of segmentors can be used, the selection of a subset allowing to limit the computational complexity and adapt the segmentor to the reference digital image to be filtered. |
