Abstract (in Japanese) (See Japanese page) 
(in English) In predictive coding,
prediction methods that aim to more efficient prediction
by switching some predictors based on local index have been proposed in the past.
The differces between adjacent pixels, i.e. gradients, are popularly used in such methods.
However, relationship between the gradients and predictors is discussed only qualitatively.
In this paper, we propose a prediction method using difference to average prediction value as local index.
In the experiments, the proposed prediction scheme shows its superiority to LOCO-I and CALIC
in terms of entropy of prediction error and code length.
Keyword (in Japanese) (See Japanese page) 
(in English) predictive coding / local characteristic / average prediction / / / / /
