Abstract :
We improve the performance of conventional motion compensated discrete cosine transform video coding. For motion compensation, we employ a two step algorithm in which the camera motion is compensated first and then the motion of moving objects is estimated. We use a feature matching algorithm for camera motion compensation. Motion compensated frame differences are divided into three regions called stationary background, moving objects, and newly emerging area. A region adaptive subband image coding scheme is used for spatial coding of these regions
