Abstract |
Although motion compensation for H.264 produces high coding efficiency through its use of multiple reference frames and macro blocks, it also increases the overall coding complexity due to the motion search for various cases. This study proposes a fast motion estimation method to obtain a motion vector able to reduce the overall coding complexity and obtain the required computation in motion search by reusing the sum of absolute difference. Experimental results show that the proposed fast motion estimation method significantly reduces the performance time, with negligible degradation in video quality. |
