ABSTRACT:
A system and a method for motion-compensated de-interlacing of interlaced video frames that generates high quality progressive video frames, keeps computational complexity low and requires the use of only a single image frame is provided. The system and method of this invention determine if global motion (camera motion) is present in the scene. If global motion is detected, it is estimated and compensated. The globally-compensated image is then analyzed to determine whether local motion is present. If local motion is detected, the image pixels affected by the local motion are interpolated using motion-adaptive techniques. If no local motion and no global motion is detected, the image pixels are interleaved.
