Abstract :
This paper proposes a fast inter prediction mode decision method for H.264. By pre-encoding a downsampled small image, the candidate inter block modes can be reduced to a small subset. The simulation result shows that our algorithm can achieve up to 50% complexity reduction with less than 0.2dB PSNR decrease.
