Abstract
An electronic processing device receives sets of image data representing respectively sequential three-dimensional digital images of the same region. This device comprises means capable of defining a three-dimensional shape of interest on the basis of at least one of the sets of image data, and of extracting from each set image data representing characteristic points of the shape of interest, processing means for establishing on the basis of the image data of the contours a spatial-temporal planispheric transformation making it possible to pass from characteristic points extracted from one image to the characteristic points extracted from another image of the sequence, and means for displaying selected motion data derived from the parameters of the transformation.
