| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | An endocytoscope provides ultramagnified observation that enable physicians to achieve minimally invasive and real-time diagnosis in colonoscopy. However, much pathological knowledge and clinical experiences are required for this diagnosis. The computer-aided diagnosis (CAD) system that decreases overlooking of neoplastic polyps in endocytoscopy is required. Texture-feature-based classification between neoplastic and non-neoplastic images of polyps has been proposed towards the construction of the CAD system. Extracted texture feature includes worthless elements that do not contribute to classification. This worthless elements can lead classification errors. We propose feature-selection method that selects discriminative feature for two-categories classification by omitting worthless feature of texture features. We experimentally evaluated the proposed method by comparing the classification accuracy between before and after feature selection with about 19,000 endocytoscopic images. The experimental results show that our proposed method gives 2.4% higher accuracy than original texture feature. | |
