This paper proposed a novel approach to segment objects from the H.264 compressed video with moving background. At first, the noisy motion vectors are eliminated from the motion field by vector median filtering. Then the predicted motion field reconstructed by backward estimation is used to accumulate the motion field, which is followed by global motion compensation. After that, the hypothesis testing...
Variable size motion estimation with multiple reference frames has been adopted by the new video coding standard H.264. It can achieve significant coding efficiency compared to coding a macroblock (MB) in regular size with single reference frame. On the other hand, it causes high computational complexity of motion estimation at the encoder. Rate distortion optimized (RDO) decision is one powerful...
