Fixed camera videos are obtained/used by surveillance, teleconference, remote lecturing. Since it is one of the most fundamental camera movement techniques, it is also frequently used in studio shots, drama/movie scenes. In this paper, simple and efficient coding method for such fixed camera videos is proposed. The proposal significantly improves the coding efficiency and generated bitstream is fully...
Lossless image coding process predicts the value of current pixel from previously decoded pixel values. Then the prediction error is classified according to the context model. This classification splits the sources with different distributions and hence reduce the total entropy of the prediction error signals. In the literature, the predictor has been intensively studied. Some evolutionary approaches...
In video coding standards such as H.265/HEVC and H.264/AVC using motion compensation, motion vector prediction (MVP) refers to motion vectors predicted from the neighboring encoded or decoded blocks. However, if the reference block is encoded in intra prediction mode, the motion vector cannot be acquired because the block has no motion information. This decreases motion vector prediction efficiency...
