Abstract :
According to spatial/temporal properties of successive frames, the correlation is analyzed between regions of interest (NonROI, NormalROI, TopROI) and macro block mode decision of AVS. The Fast Region-based Inter Mode Selection Algorithm (FRIMS) is proposed to reduce computational complexity and speed up the codec. The simulation results show that FRIMS can save about 60% of encoding time with little loss of PSNR and bit rate, when using 2 reference frames. FRIMS can be applied to other block-based video codec (like H.264 etc) with ease.
