Abstract
Recent results show that the parallel processing capability of the powerful Graphics Process Unit (GPU) can greatly accelerate motion estimation in H.264/AVC encoder implementation. However, the bit rate cost of motion vector (MV) is always ignored in this parallel motion estimation implementation on GPU due to the unavailability of the spatially predicted MVs, which accordingly degrades the rate-distortion performance. In this letter, a novel collocated macroblock based motion estimation algorithm is proposed to tackle this problem by using temporally predicted MV. The experimental results demonstrate that the peak signal-to-noise ratio (PSNR) improvement can be up to 0.8 dB with a negligible computational complexity increase.
