摘要
- method for forming, on the basis of data obtained by scanning a zone of a heterogeneous medium (an underground zone, for example), a model representing the distribution in the area of at least one physical quantity which is largely free of the presence of noise correlated to perturb the data. - the method comprises the following steps: - acquisition of data concerning certain characteristics of the zone; - specification of modelling operator which, in a model, the response of the model (synthetic data); - modeling each noise correlated with the application, to a function of the noise generator (f.g.b.), a modelling operator specific; - specification of a semi - standard in the space of the data; - specification, in each space of f.g.b, of a standard for which each modelling operator of the noise is an isometric; and - search, by a method of algorithmic pulling portion of these properties by isometry, the model and the f.g.b. which minimize a cost function quantifying, by means of the semi-finished - standard, the difference between the measured data and the superposition of the response of the model and noise associated with the f.g.b. - applications, for example, to the search for the distribution in an underground zone, of the acoustic impedance of the propagation speeds, permeability, etc, 1 / p
