Method in order to facilitate the recognition of objects, in particular geological, by a technique for discriminant analysis

摘要

- method to facilitate the recognition of objects in which it uses a technique for discriminant analysis in order to classify them into categories defined. - it forms a learning base of the objects already identified and classified into different categories defined, each of them being defined by the variables are known. It is constructed by reference to the learning base, a function of the classification by a technique for discriminant analysis, making it possible to distribute into the categories, the different objects to be filed on the basis of measurements available on a certain number of parameters. This function is formed by determining the probabilities of the objects to the various categories of taking account of the uncertainties on the parameters in the form of intervals of variable width. It is then, if possible, each object to one or several categories defined as a function of the relative value of the intervals of probability. - applications to the recognition of objects in an underground geological formation, the image processing, to the processing of the signal (for example to the remote sensing, in medical imaging, etc.).
