Adaptive Skipping Frame in TMN8 Rate Control

The skipping frame algorithm in TMN8 rate control only depending on buffer state regardless of image characteristic, may skip important frames with large motion and, as a result, video quality seriously reduced. An adaptive skipping frame algorithm is proposed for low-bit rate real-time video encoding. The occurrence of frame skipping is jointly dependent on the temporal and spatial contents of the video, and achieves a balanced spatial and temporal quality to enhance the overall perceptual quality. Experimental results show that the proposed algorithm can achieve the better subjective and objective video quality than TMN8s algorithm, without introducing any computation complexity.
