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 segmentation and binarization techniques. We propose an improved algorithm of segmentation based on region growing so that the segmentation result cannot receive bad influences from color gradation. We also propose an algorithm of binarization that is composed of edge feature, stroke width transform, and connected component analysis. 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.
