Temporal in loop filters present one possible way to reduce noise introduced in compressed video sequences at low bit rates. Some of these filtering approaches make use of the quantized and generally noisy motion information conveyed in the bit stream generated by the encoder. One key feature of such filters is an adaptive filter length depending on the image content and the quality of the motion...
Most in-loop filters currently being employed in video compression algorithms use spatial information from a single frame of the video sequence only. In this paper, a new filter is introduced and investigated that combines both spatial and temporal information to provide subjective and objective quality improvement. The filter only requires a small overhead on slice level while using the temporal...
