According to the invention, the method of primary processing of a first set of primary data (IM,f) representing physical quantities includes:a set division step (200A to 202) during which the first set of data is divided into sub-sets of first data, andfor each first sub-set of data:a step (205 to 207) of "constructing" a global contractive mapping of the first type, for the said first sub-set of data, whose fixed point constitutes an approximation of all or part of this sub-set. The set of parameters (ai, b) thus determined constitutes a primary representation of the said first set of data.
