Abstract
A method and device that operates in accordance with the method are provided for primary processing a set of data (IM, f) representing physical quantities. The method comprises a step of constructing a global contractive mapping of a first type for the set of data, the fixed point of which constitutes an approximation of all or part of this set. At least one mapping belonging to the group of mappings consisting of multi-dimensional mappings and non-linear mappings is employed to construct the global contractive mapping. A next step includes determining parameters (a , b) of the global contractive mapping so as to allow the use of a method of successive approximations converging towards the fixed point of the global contractive mapping. The determined set of parameters (a , b) constitutes a primary representation of the set of data.
