Abstract :
A low-complexity early termination algorithm for mode decision in H.264 is presented. The proposed algorithm is based on the statistical distribution of per-pixel motion cost, and it can skip the mode decision of the candidate macroblock modes with low probability. Simulation results reveal that the proposed algorithm can reduce the encoding time by 16.25% on average with the limited performance loss of about 0.023% dB.
