Abstract

The amount of documents in electronic formats has dramatically increased because of the ease of information sharing. Hence, it is highly desirable to design an efficient document compression technique. In this paper, a divide-and-conquer technique is propose to classify a local region into uni-level, bi-level and multi-level classes. As a result, various compression approaches can be applied to suitable area to increase compression efficiency. The color sigma filtering technique is adopted as a preprocessing stage to facilitate the following segmentation and cluster validation processes. Experiment results demonstrate that this technique successfully dichotomize a color document into regions with similar characteristics.
