This paper presents a bottom-up approach for segmenting document images and labeling the segmented regions with logical names. Our method uses image features in terms of the characteristics of text lines, such as margin and character size, then our method can analyze an unstable document image that has floating elements such as figures and tables. Experimental application of this method to images of technical journals written in Japanese yielded classification rates of 98.6 % for the front pages and 90.0 % for the final pages that have floating elements.
