Abstract
The present invention includes a method for processing an intensity image (J.sub.0) formed of points representing an object (LV), including steps for automatically supplying points so as to determine a minimum path representing the object contour (CT), involving: acquiring data of the intensity image, evaluating probability values (P) indicating the probability that a given point of the image belongs to predefined regions of the image relating to the object, and deriving a contour model (SP) of the object from said probability values (P), transforming the image (J.sub.0) into a three-dimensional matrix image (IM) based on said contour model (SP) and said probability values (P), performing dynamic programming (DP) in order to determine said minimum path (CT) in said three-dimensional matrix image (IM).
