Abstract:
The method of coding a multidimensional digital signal, said signal comprising a plurality of samples denoted “initial”, characterized in that it comprises: —a step of determining at least one secondary signal representing said multidimensional digital signal, each secondary signal having a lower number of samples than the number of samples of the multidimensional digital signal; —a step of determining filtering orientations on the basis of at least one secondary signal and—a step of determining at least one tertiary signal representing the signal to code, each tertiary signal having a lower number of samples than the number of initial samples, by implementing, on said multidimensional digital signal, filtering that is oriented on the basis of said filtering orientations.
