SYSTEM AND METHOD FOR PROCESSING AT LEAST ONE POLLUTING REGION OF A DIGITAL IMAGE OF AN OBJECT EXPOSED TO X-RAYS

摘要

The invention relates to a system and method for processing a polluting region of a digital image of an object (3) acquired using X-rays and comprising points (P) with each of which there is associated a numerical intensity value and at least one item of metadata (M) chosen from among one or more physical parameters of the object, and one or more parameters relating to the power or the energy of the X-rays with which the image was acquired. Said method comprises identifying at least one group of points in the image corresponding to a polluting region on the basis of the initial intensity values I0 of the points in the image and of said metadata. Generating a new image comprises a step of replacing the initial intensity values I0 of at least some of the points of said at least one polluting region with new intensity values.
