| Popis: | 95 The newest video coding standard called H.264 provides considerable performance improvement over a wide range of bit rates and video resolutions compared to previous standards. In H.264, the motion estimation module occupies the largest computational complexity in an encoder, and it supports seven various block sizes with a tree structured macroblock partition. In order to reduce the computational complexity of motion estimation in H.264, Priority-Based Normalized Partial Distortion Search Algorithm for Fast Motion Estimation, Adaptive Search Range Decision, Search Method Decision and Early Termination for Very Low Motion MBs are proposed in this thesis. Experimental results show that the proposed algorithms provide significant coding time improvement with only slightly PSNR degradation compared to several fast motion estimation algorithms which are implemented under the JM12.2 reference software platform. |
