Scene-Cut Processing in Motion-Compensated Temporal Filtering

Motion-compensated temporal filtering (MCTF) is a powerful technique entering scalable video coding schemes. Its performance decreases significantly however if the the video signal correlation is poor and in particular when scene-cuts occur. In this paper, we propose an improved structure for MCTF by detecting and processing the scene-cuts that may appear in video sequences. It significantly reduces the ghosting artefacts in the temporal approximation subband frames, providing a higher quality temporal scalability, and dramatically improves the global coding efficiency when such abrupt transitions happen.
