Abstract

This paper presents an efficient lossless data compression scheme for various kinds of binary images as line drawings and half-tone pictures. We studied a combination of preprocessing and Lempel-Ziv universal coding. To improve the compression ratio, we modified Lempel-Ziv universal coding by dividing its dictionary into classified sub-dictionaries. We obtained improved compression ratios in computer simulation on composite images consisting of mixed test and images.
