Radiographic data are examined as landscapes, the third dimension representing pixel intensity. Two processing chains are used in parallel, the first applying linear transformations to the original image and the second non-linear transformations. A first smoothing of the original image at the resolution of the images is used to provide lists of local peaks. A second smoothing at the resolution of the diffuse objects identifies regions of homogeneous intensity and lists of peaks in decreasing order of intensity. A final list is prepared from the results of each of the two processing chains which are operated in parallel.
