This paper presents a new fast motion estimation method where search ranges are determined by the probabilities of motion vector differences (MVDs). The MVDs' distribution is investigated and its parameter is estimated by the maximum likelihood estimator. With the estimated distribution, the search ranges is efficiently restricted by a prefixed probability for MVDs. Experimental results show that...
In hardware implementation of a video coding system memory access becomes a critical issue and the motion estimation (ME) module is the one which consumes most of the data access. To meet the requirements of HD specification, conventional data reuse schemes are not sufficient. In this paper, the hierarchical approach to ME is combined with the Level C and D data reuse schemes. Proposed two-level hierarchical...
With the advent of new video standards such as H.264/AVC, the demands for low-complexity advanced video coding (AVC), particularly for the subfunction of variable block searching motion estimation, is increasingly important for efficient system designs. The motion estimation needs heavy computations and many external memory accesses which are the main sources of the system complexity and power consumption...
