Abstract(in English) This paper proposes a new intra prediction method which can be used with block-based image coding techniques such as DCT. In the conventional intra prediction methods specified in H.264/AVC and HEVC, a predicted value at each pel is typically calculated from a few reference pels located at fixed positions. Therefore, it is difficult to generate a smooth predicted image which could be obtained by weighting a large number of the reference pels. On the other hand, our method calculates prediction coefficients for all of the reference pels according to mean value coordinates of the respective pels to be predicted. This procedure imposes no restriction on disposition of the reference pels and, as a result, various types of intra prediction can be performed even if the coding order of blocks is adaptively changed.
