Motion-compensated frame interpolation scheme for H.263 codec
نویسندگان
چکیده
The temporal jerkiness removal for the H.263/H.263+ video conferencing system is the main object of this research. We proposed a fast block-based motion-compensated frame interpolation (FMCI) scheme which does not require any motion search in the decoder end, and therefore the complexity is low enough for achieving the real-time frame rate increase. In order to further improve the visual quality, we proposed two add-on schemes to enhance the FMCI, the adaptive frame skip (AFS) scheme in the encoder and the hybrid scheme of frame interpolation (HFI) incorporating both frame repetition and FMCI in the decoder. By adopting the two add-on schemes, we can successfully avoid the failure of FMCI prediction and achieve the smooth playback.

Global/Local Motion-Compensated Frame Interpolation for Low Bitrate Video
A new motion-compensated frame interpolation scheme for low bitrate video based on the ITU-T H.263/H.263+ standard is investigated in this research. The proposed scheme works solely on the decoded bitstream with a blockbased approach to achieve interpolation results. It is composed of two main modules: the background/foreground segmentation module and the hybrid motion compensated frame interpo...

Common motion compensated hybrid video coding standards such as H.263, MPEG-1, MPEG-2, MPEG-4 are based on a fractional-pel displacement vector (DV) resolution of 1/2-pel. Recent approaches like MPEG-4 (ACE-profile) and H.26L use higher DV resolutions of 1/4-pel and 1/8-pel. In order to estimate and compensate fractional-pel displacements, the image signal has to be interpolated. Especially for...
