Abstract
For object-oriented analysis-synthesis coding an image analysis algorithm is required which automatically generates the parameter sets which describe moving 3D objects in an image sequence. Areas changed between two consecutive images are detected by means of change detection. Special processing is carried out to compute areas which coincide with object boundaries and to eliminate areas which represent illumination changes. These areas are segmented into silhouettes of moving objects and uncovered background. The border of an object silhouette is interpreted as the outermost contour of an object. These contours in combination with a simple function giving the z-distance between them provide a first estimiate for 3D shape of a model object. In order to improve the efficiency of motion analysis a concept for combining model objects with new parts of moving objects is proposed. Results of an automatic image analysis based on moving 3D objects are shown using video telephone test sequences.
