Motion-compensated temporal filtering with optimized motion estimation

Abstract: The lifting-based discrete wavelet transforms applied temporally along the motion trajectory is a powerful tool in scalable video compression. The longer filter is used for motion-compensated temporal filtering (MCTF) for better de-correlation. The bidirectional motion estimation (ME) used for MCTF is the major speed bottleneck. This paper propose two stages motion predictive technique to optimize the ME. In the first stage, zero motion block prediction is carried out using the content of high frequency frame,… Show more
