- In this study, a computation-aware scheme for motion estimation (ME) in H.264 is proposed. The objective of the proposed scheme is to properly distribute the available ME computations of the H.264 encoder. Here, the temporal motion vector prediction technique is used to get the predicted motion vector (PMV) of each macroblock (MB). The sum of absolute components of the PMVs of all the MBs in a video frame is used as the measure to allocate the target computation to a video frame. The proposed scheme contains four phases: 1) frame-level computation allocation, 2) MB-level computation allocation, 3) mode-level computation allocation, and 4) pixel-level computation allocation. As compared with the comparison scheme, the proposed computation-aware schemes for motion estimation in H.264 usually have the better performance (average PSNR improvement and bit rate increment) in most simulation cases.
