Abstract
The invention relates to a method of processing a digital signal comprising samples (a.sub.1, a.sub.2, . . . , a.sub.9) each represented by a coordinate on each axis of a coordinate system with n dimensions, where n is the dimension of said digital signal, characterized in that it comprises the following steps: determining among the coordinates of said samples the extreme coordinates (L, R, B, T) on each coordinate axis (x and y) of the coordinate system, for all the possible combinations between said samples taken in pairs, determining a minimum distance among all the distances calculated along each axis between, on the one hand, the coordinate of a first sample, and, on the other hand, the coordinate of each of the elements of the group comprising a second sample and copies of this second sample obtained by translation of said second sample in different directions and according to a value which depends on the extreme coordinates already determined.
