4-3 事例ベースの確率モデリングによる静止画像の可逆符号化の検討(第4部門 メディア工学2)

抄録

High efficient lossless coding schemes typically employ some kind of prediction technique to decorrelate image signals. In this paper, we propose another approach which directly encodes the image signals without prediction. A probabilty density function of the image value at each pel is estimated based on several examples obtained by template matching in its causal area.
