Abstract (in Japanese) (See Japanese page) 
(in English) The purpose of this research is to extract the characters from color document images with complex background such as journal covers by using color quantization and binarization techniques. We propose an improved
algorithm of color quantization based on the saliency map by Achanta’s algorithm and the modified versionof the Ong’s SOM. We also propose an algorithm of binarization in which each color of character is once separated toextract the characters in each color plane and then extracted results are integrated to produce the binarized image.To demonstrate the effectiveness of the proposed method, we perform the comparative experiments in comparison
with the other methods using the quantitative evaluation with Ground Truth.
