Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a pulmonary nodule detection method from X-ray CT images using discrimination filters. First, we use circle-ring-shaped linear discrimination filters that are two-layered concentric circulation filters based on Fisher linear discriminant functions. False positives are reduced by radially arranged rectangular filters and pixel-based Support Vector Machine.Experimental results are shown the effectiveness of the suggestion technique.
