| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The purpose of this study is to develop a computer-aided diagnosis (CAD) system for early detection of arteriolar narrowing on retinal images. Our scheme consists of extraction of blood vessel, classification of artery and vein, and detection of arteriolar narrowing by the artery-vein diameter ratio. The classification of artery and vein is important for improving the performance of the detection. However, the features used in the classification depend on the position of the image and the variation of the features negatively affects the classification accuracy. In order to solve this issue, we propose a technique to reduce the variation of the features by use of top-hat image in the feature extraction. Eighty-three images were used to estimate our scheme. As a result, the sensitivity for detection arteriolar narrowing was 76% with 1.4 false-positive vessels per image. Therefore, the technique we proposed in this study may be useful for detection of arteriolar narrowing. | |
