Abstract :
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. In this paper, a hardware design of type identification module in CAD system for colorectal endoscopie images with narrow band imaging (NBI) magnification [1] is proposed for real-time processing of full high definition (Full HD) image (1920 × 1080 pixel). In this paper, 2-step Identifier with SVM to realize a 3-class identification, which occupies small circuit area and achieves high accuracy, is proposed.
