Abstract
Frame rate up-conversion (FRUC) is a post-processing tool to convert the frame rate from a lower number to a higher one. It is a useful technique for a lot of practical applications, such as display format conversion, low bitrate video coding and slow motion playback. Unlike traditional approaches, such as frame repetition or linear frame interpolation, motion-compensated frame interpolation (MCFI) technique which takes block motion into account is regarded as a more efficient scheme. By considering the deficiencies in previous works, new criteria and coding schemes for improving motion derivation and interpolation processes are suggested. In addition, adaptive frame skip is fulfilled at the encoder side to maximize the power of MCFI in video coding applications so that the quality of interpolated frames is guaranteed. Experimental results show that our proposal indeed enhances the overall quality, both subjectively and objectively, of the frame rate up-converted video sequence.
