Research of Non-dilated Fundus Images for Automated Diabetic Retinopathy Screening
摘要
Abstract
In order to realize automatic screening for diabetic retinopathy ( DR ) , an automated diabetic retinopathy screening system based on non-dilated fundus images is proposed and studied. Firstly, the composition and key technol-ogy of the system including locating and extracting optic disc and automated detection of hard exudates, cotton wool spots, hemorrhages as well as microaneurysms were analyzed and reviewed. Then the system based on non-dilated fun-dus images was developed and tested on an image dataset collected in clinic which include 7 687 samples in total of 15 374 fundus images. With an exam-based criterion, sensitivity of 96. 46%, specificity of 96. 07% are achieved. Fur-thermore, the average time cost in processing a sample is 57. 87 seconds. Results suggest that the performance of DR screening system meet the minimum standard of 80% sensitivity and 95% specificity for the detection of sight-threaten-ing DR which was recommended by British Diabetic Association guidelines.关键词
