Abstract

DjVu is a document codec that uses a truncated embeddedsignificance tree to achieve both resolution and imagequality scalability. In this paper, the probability model forthe truncated tree arithmetic coder is improved, resultingin reduced bit-rates. The trade-off in decoder complexity isalso indicated.
