Motion hints compensated prediction as a reference frame for high efficiency video coding (HEVC)

摘要

Segment-based temporal prediction combined with higher-order motion models have been studied as an alternative to conventional block-based translational inter prediction. One example of such studies is known as motion hints, where an affine motion model has been used. In this paper, we explore the applicability of motion hints with an elastic motion model in generating reference frames for conventionally coded B-frames. The presented design enables the re-use of existing codecs, such as HEVC, without modifications in low-level coding tools. Experimental results show that a savings in bit rate of up to 5.1% is achievable over standalone HEVC with increased computational complexity.
