Xin Dong · Jisuanji gongcheng yu sheji · 2011
The principle of motion estimation in H.264 is introduced and the difficulty of the four classical motion estimation algorithms is discussed when applyed to the video compressing and transmitting of angiography.Then the four motion estimation algorithms above are analyzed to improve compression ratio and the rate-distortion of reconstruction video of angiography,and the algorithms above are programmed in the JM.The experimental results using clinical data show that UMHexagonS algorithm reaching equilibrium at high compression ratio and better rate distortion and is more suitable for the video compressing and transmitting of angiography.
