18-3 DCT符号化における係数単位の内挿予測方式(第18部門 画像符号化)

抄録

This paper describes a new intra prediction method which is designed to exploit inter-block correlations for DCT based image coding. By changing a coding process of DCT coefficients from block-wise order to coefficient-wise one, the method can benefit from interpolative prediction in almost all blocks.
