Linear Algebra and Its Applications
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 proposed 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. As a result, compression efficiency can be improved by choosing the appropriate compression technique according to the classifications of the local regions. Experimental results demonstrate that this technique successfully classifies a color document into regions with similar characteristics. © 2002 SPIE · 0277-786X/02/$15.00.
