Abstract
Method of improved detection of elements of interest by means of a detection system in a digital radiographic image of an object, acquired on an acquisition chain, comprising a first calibration phase in which the performances of the detection system are established. For such purpose, a calibration curve with several dimensions is determined by means of a mathematical model of the acquisition chain and object, in order to express a false positive probability as a function of a set of parameters corresponding to the acquisition chain and object. In the course of a second phase of use, a false positive probability value is determined for each pixel of the image. One then selects among the pixels of the digital radiographic image acquired those whose probability value obtained satisfies a predetermined criterion.
