    • The present invention concerns a method of coding a plurality of digital image signals in a bitstream, said signals each corresponding to a view of a scene, the said coding method comprising the use of a pre-determined predictive coding structure, the views being associated with input views in the coding structure. The coding method according to the invention comprises, for at least one pair of views of the scene, steps of determining a spatial intersection zone (E44) and of calculating a value representing the similarity between the signals corresponding to said views (E45), according to at least some of the signals contained in said spatial intersection zone. These steps are followed by a step of associating (E46) at least one view with an input view of the predictive coding structure according to at least one calculated similarity value. The invention applies both to fixed image signals and to image sequences.
