Consideration of the Image Area Separation Algorithm using Markov Model Context

Abstract

Owing to development of the printing and scanning technology the opportunities to treat a mixed image of the photograph and character are on the increase. However, the file size of high-resolution document image is usually large, and costs of communication and storage increase. Therefore a document image is classified into a character region and photograph region, and encode them by the suitable method for each region. In this paper, we propose a classification method into a character region and a photograph region from the mixed image by using Markov model contexts.
