PROCEDE D'ESTIMATION DU MOUVEMENT DANS UNE SEQUENCE D'IMAGES DYNAMIQUES |
摘要 |
The method involves calculating movement of corners of rectangular regions of interest using differences of phase components between two successive images of a phase image sequence at two instants, where the phase image sequence is calculated from a dynamic image sequence. Eight parameters of a local bilinear transformation of a movement vector are calculated to calculate dense motion fields by bilinear interpolation in all points of meshes of a regular rectangular grid of the phase image sequence. The dense motion fields are displayed on the images of the dynamic image sequence. |
