| Abstract(in English) | Fundus oculi image is quite significant window of human body to observe its vascular system directly from outside. Through it, we can obtain important information on disease in early stage. Here, as an trial to analyze such image, an automatic detection of soft-drusen region is performed. After shading compensation of fundus image, pathological candidate point is selected by using the spatial characteristics of fundus image under the assumption that drusen region is described as an bright area in the picture. Then by the guidance of these candidate points, the original image is inspected again by using adaptive threshold technique. The result obtained by this rather simple procedure is compared with the decision by the oculist, and about 80% of them had good coincidences. It must be suggested a little improvement of the procedure bring us a useful supporting system for drusen diagnosis. |
