Improving motion compensation using multiple temporal frames

Video compression with intra/inter mode switching and a dual frame buffer

“…The idea of using more than one past reference frame to improve coding efficienc y is not new. The first mention [3] of multiple reference frames dates almost a decade back; it was shown that the meansquared error (MSE) between the current frame and the predicted one strictly decreases by using multiple temporal frames for motion compensation. Another early attempt to code an image using a so-called library of past frame components can be found in [2], and made use of vector quantization.…”

Video Coding with Superimposed Motion-Compensated Signals

“…In recent years, advances in compression efficiency have mainly been achieved by improved motion-compensated prediction, e.g. sub-pel accurate motion compensation [Gir93a], variable block size prediction [SB91b], multiframe prediction [GV93,BG96,WZG97a], and multihypothesis motion compensation.…”

Dual frame motion compensation for a rate switching network

“…The idea of using a long-term past frame as an additional reference frame for motion compensation was considered in several papers [2], [3], [4], [5] as well as in the recent H.264 standard. [2] is one of the earliest papers to employ multiple frames for motion compensation to reduce the number of bits required to code the difference signal.…”
