H.264/AVC introduces the variable block size macroblock mode for motion estimation, which brings huge computational cost. In this paper, a novel fast inter macroblock mode decision algorithm for H.264/AVC has been proposed. The proposed algorithm evaluates the modes based on residual information. The residual is obtained after the motion search of P16 ?? 16 mode or P8 ?? 8 mode. Then the characteristic...
Since H.264 is a high performance coding standard in with high computational requirements, it is hard to implement on portable devices. According to the human visual system (HVS) research, human eyes can only focus on one area in a frame, which is called region-of-interest (ROI). This phenomenon gives a chance to code all macroblocks unequally. In this work, the ROI is detected using texture contrast...
H.264 is the state-of-the-art in modern video compression standards. Its extremely high compression ratio meets the requirements the video communication between portable devices. Since the power is limited in portable devices, the huge computation of H.264 is a critical problem for hardware design. According to the human visual system (HVS) research, human vision is only able to focus on one area...
