文摘
Block based motion estimation is usually used to reduce the computational complexity while preserving a good quality of the images used in real-time video coding. A new block matching motion estimation algorithm called star diamond search is proposed in this paper. This one proceeds in two stages: the first one consists in carrying out a search having star shape. This one aims a coarse search for the solution, the second phase consists in refining the search for the solution. A comparative study with the most known methods is given showing the interest of the proposed algorithm.
