- W1993059464 abstract "Traditional video coding uses fixed keyframe setting, which cannot exert all the potentials of inter-frame prediction. Dynamic adaptive keyframe setting can improve the efficiency and quality of video coding. However, it generally requires time-consuming preprocessing of video analysis, which prevents it from being practical. In this paper, we propose a novel method of keyframe setting: <i>Fast Dynamic Adaptive Keyframe Setting</i>. The method adopts a quasi single-pass strategy of exploiting information generated by original motion-estimation, so the additional computing costs are acceptable. The method can improve both objective and subjective quality, and can be applied to any motion-estimation based video coding. Experimental results on both MPEG-2 codec and H.264 codec prove that the method is viable and valuable." @default.
