A new method that uses a modified fractal dimension theory to segment a document image and to discriminate between Oriental and European languages is presented in this paper. Two types of techniques have been usually adopted in language discrimination: token matching and statistical analysis. A modified fractal feature is used to discriminate the distinct textual structure complexities of Oriental and European languages. Experiments show that this method is effective and reliable for processing the document image even if it is skewed or contains noise that can not be removed clearly.
