RESULTS

As a first example, we present a digitised image from a TAC where the contour of a kidney has to be found. The external contour shown in figure 1, is determined by some pre-established initial control points. They will become the starting point of the whole process. On the other hand, the internal contour is the final B-snake, the result of the processing. The initialisation of the contour in these experiments has been made manually, by means of an interactive program.

In next example, a vertebra contour has to be found. To accomplish this goal, a process of minimization is applied to the initial contour shown on figure 2. The final contour obtained is shown in figure 3.
