Qコーダを用いた2値画像の可逆型順次符号化法

抄録

PABIC, a technique for progressive coding and transmission of binary images, is presented. This technique uses the majority and center rules for image size reduction and the Q-Coder for coding. On standard CCITT documents, IBM's ABIC algorithm, applied independently to each reduced copy of the image, produces about 30% longer code than PABIC. While giving on average 2% worse results than Japanese KDD algorithm, PABIC has simpler and faster software implementation and less complex hardware design as well.
