PROCEDE D'EXTRACTION D'EMPREINTES AU SOL D'OBJETS DANS UN MODELE NUMERIQUE D'ELEVATION A L'AIDE DE CONTOURS ACTIFS NON PARAMETRIQUES

摘要

A set of active contours is acquired (1) in relation a movement law. Movement of the active contours is acquired (2) when these fulfil a first condition so as to determine first positions, followed by starting new movement (3) along active contours according to the movement law. The movement is stopped (4) when a second condition is attained, so as to determine second positions.
