3次元形状モデルを用いた動画像のフレーム内挿方式

抄録

A reduction of the number of transmitted frames can often be adopted in a low bit-rate coding (64kbit/s) of videophone images. However, the transmitted images may have a lot of jerkiness, if the period between the transmitted frames is long. This paper, from the viewpoint of application of model-based image coding techniques to waveform image coding, proposes a new frame interpolation method for moving images based on a 3-D-shape model of an object and its 3-D motion vector. Firstly, the basic framework of the proposed frame interpolation method is presented. Secondly, the 3-D motion estimation method and the frame interpolation method using a 3-D model are described in detail. Finally, we give experimental results showing that the proposed method is an effective frame interpolation method.
