Method of extraction of impressions on the ground of objects in a non-limitative model of elevation, with the aid of active contours not parametric

摘要

Method of automatically extracting impressions on the ground of objects, in particular of man-made structures, within a digital model of elevation, consisting in: to change a set of active contours which obeys a law of order to store the positions of each of these active contours when - latter is filled with a first stop condition, be of a new change the set of active contours according to the law of variation, the evolution of the active contours when those - it to fulfill a second stop condition.
