| Abstract(in English) | In this report, a coefficient-parameter-reduction method is proposed for invertible deinterlacing with variable coefficients. Invertible deinterlacing, which the authors have developed, can be used for interlaced video as preprocessing of frame-based motion picture codec, such as Motion-JPEG2000 (MJP2). When simple conventional field-interleaving is used, comb-tooth artifacts may appcar around edges of motion objects. 0n the other hand, the invertible deinterlacing technique allows us to suppress comb-tooth artifacts and also to restore an original picture on demand. As previous works, the authors have developed a variable coefficient scheme with a motion detection filter, which realizes adaptability to local characteristics of pictures. When applying this deinterlacing technique to an image codec, it is necessary to send coefficient parameters to receivers for original picture recovery. This report shows that these coefficient parameters can be reduced by decimating horizontally without significant loss of comb-tooth suppression ability. |
