PROCEDE ITERATIF D'ESTIMATION DE MOUVEMENT, ENTRE UNE IMAGE DE REFERENCE ET UNE IMAGE COURANTE, ET DISPOSITIF POUR LA MISE EN OEUVRE DE CE PROCEDE

摘要

This iterative method for estimating movement consists of carrying out a fixed number of iterations, each iteration consisting of: sampling (8, 9) both images with a resolution which increases for each iteration; detecting characteristic samples in the reference image (11'); estimating a local movement vector (14') for each characteristic sample of the reference image, by initializing this estimation with a movement vector deduced from an estimation of overall movement, carried out during the iteration preceding the current iteration; making an estimation of the overall movement of the current image, by calculating the parameter values of a model (13') from the local movement vectors estimated during the previous iteration.
