Abstract (in Japanese) (See Japanese page) 
(in English) With the increase of colorectal cancer patients in recent years, the needs of quantitative evaluation of colorectal cancer are increased, and the Computer-Aided Diagnosis (CAD) system which supports doctor's diagnosis is essential. This paper describes type identification module in the above CAD system for colorectal endoscopic images with narrow band imaging (NBI) magnification. In type identification module, the raster scan of a colorectal endoscopic image with Scan Window (SW), is carried out and the type identification of each SW is performed. In this paper, we propose a hierarchical type segmentation algorithm which realizes improvement in accuracy and resolution with combination of different SW sizes. The simulation results are also presented for the cases in which the feature extraction is performed in dense and rough for small and large scan window sizes, respectively.
