Abstract
Diabetic retinopathy is a major cause of blindness in working age population and exudates are considered the most significant characteristics of diabetic retinopathy. Therefore, automatic exudate detection is beneficial to large-scale diabetic retinopathy screening. In this paper, an automatic approach for detection of exudates on color fundus images is presented and discussed, which is based on the thresholding technique and Kirsch’s edge detection. Besides, a color space conversion step (from RGB to YIQ) is utilized to improve the detection performance. The method is evaluated on a public dataset of fundus images from various ethnic groups. We obtain an average sensitivity of 75.17% and an average specificity of 97.98%, which outperforms the baseline method and validates the effectiveness of the proposed method.
