Abstract

A fast block-based motion-compensated frame interpolation (FMCI) scheme was proposed in our previous work. FMCI does not require any motion search in the decoder so that the complexity is low enough to achieve frame rate increase in real time. To further improve the visual quality, we propose two add-on schemes to enhance FMCI in this research. They are the adaptive frame skip (AFS) scheme applied at the encoder and the hybrid frame interpolation (HFI) scheme which incorporates both frame repetition and FMCI at the decoder. By adopting these two add-on features, the enhanced FMCI method is made more robust to allow smooth playback
