To follow the movements of a face using a method based on reconstructing a 2D model, an initialization method comprises a search for symbolic points on successive images of the face forming a sequence of images. Each symbolic point detected on a current image is stored together with its imagette extracted from the current image and, when all the symbolic points desired have been detected at least once in the sequence of images, the initialization is terminated by registration of the imagettes on a current image and a specific 2D model of the face is constructed. The method makes it possible to begin the tracking phase before the initialization phase is terminated, in particular when at least two symbolic points have been identified in the sequence of images. |
