Abstract
A digitized secondary image which promotes predetermined elements of interest of the object is created from each primary image, digital processing for two-dimensional mutual resetting of the secondary images is carried out per pair of consecutive images, for each current reset secondary image a region common to the said current image and to the following reset secondary image is defined which is bounded by the two respective median horizontal lines of the two reset secondary images, and the digitized overall radiographic picture is created from the upper region of the first reset secondary image of the succession, lying above the common region of this first image, from the lower region of the last reset secondary image of the succession, lying below the common region of this last image, and from the common regions of each pair of reset secondary images.
