Abstract
A device includes a registration module that determines a registration transformation between a first set of data of a first image and a second set of data of a second image. A sampling module re-samples the first set of data into a third set of data able to be superposed directly, sample by sample, on the second set of data. A processing module determines, starting from the second and third set of data, a set of difference data representing differences between superposable areas of the images constituted by the second and third sets of data.
