Computer tool characterised in that it comprises: a working memory (206) to receive input data, an auxiliary memory (204) to store several approximation dictionaries, a reducer (202) arranged for the iterative calculation of the approximation data of the input data, where the successive iterations are of the “matching pursuit” type, a selector (200) arranged to choose an approximation dictionary in the auxiliary memory based on a selection rule based on at least some of the preceding iterations, in which the reducer (202) calls the selector (200) in each iteration, and uses the dictionary thus selected in the adaptive matching. |
