Abstract
In this paper, the problems of motion field estimation and motion compensating interpolation are considered. It is shown that motion temporal projection increases the accuracy of the motion estimation when used as a temporal prediction. Moreover, this process carries information about the occluding, appearing and disappearing areas. A label field is introduced in order to emphasize and memorize this information, and a simple method leads to the detection of such areas. In a second step, the motion and label fields are used for motion compensating interpolation. Motion temporal projection is used to define the motion field of the image to be interpolated. The information carried by the label field is propagated along the motion vectors in the image to be interpolated. This procedure leads to detect the foreground objects and correctly estimate their motion, and to detect the appearing and disappearing areas and adapt the interpolation to these particular areas.
