The technique of variable block-size motion estimation is employed in the H.264 international video coding standard to obtain better compression performance. However, this technique brings about a lot of increase in the computational complexity and thus is very time-consuming. For this reason, a new fast motion estimation mode decision algorithm is proposed in this paper to reduce the computational...
H.264 is most likely the future standard for the web-based applications of video streaming and browsing. The block motion estimation process is a very time consuming part in the H.264 video coding standard and thus hinders its real-time applications. Therefore, a new fast block motion estimation algorithm is proposed in this paper. In this algorithm, it first determines the current block as a quasi-stationary,...
The UMHexagonS algorithm has been accepted for the block motion estimation process in the H.264 video coding standard due to its high accuracy and low computational requirement. In this paper, a new algorithm is proposed, which improves on the UMHexagonS algorithm in three aspects. Firstly, a new prediction vector is added for avoiding being trapped in a local minimum. Secondly, the 5×5 full-search...
The block motion estimation process is a very time consuming part in the H.264 video coding standard and thus hinders its real-time applications. Therefore, a new fast block motion estimation algorithm is proposed in this paper. In this algorithm, it first determines the current block as a quasi-stationary, slow motion, or fast motion block. Then, according to the different motion types, different...
