Abstract
A new video synthesis method is proposed. In this method, the key for extracting moving objects is given in the first frame. In the following frames, the key is moved and transformed according to the detected motion-vector of the objects. Then with this transformed key, the objects are extracted automatically and synthesized. A motion-vector detection method suitable for this synthesis is discussed. According to the experiment using motion pictures with pan, tilt, zoom, and rotation, the matching method obtains an error smaller than ±2 pixels with detection points of 4 distant areas on the edge of the objects. It is confirmed that this synthesis method can be achieved at a video-rate on the real-time video signal processing system called the Picot-system.
