Abstract (en)
[origin: WO2007027012A1] A method of reducing mismatch between an encoder and a decoder in a motion compensated temporal filtering process and a video coding method and apparatus using the same. The video coding method includes the steps of dividing input frames into one final low-pass frame and at least one high-pass frame through a motion compensated temporal filtering, coding the final low-pass frame and then decoding the coded final low-pass frame, re-estimating the high-pass frame by using the decoded final low-pass frame, and coding the re-estimation high-pass frame.
