Abstract:  To overcome the difficulties of the detection of hard exudates(HEs) such as uneven illumination, low contrast and the interference of soft exudates, a method based on SVM is proposed. Firstly we use morphological and thresholding methods to coarsely segment the candidate HEs regions in fundus images, then extract features on the candidate regions and import the AMFM features, finally we use a SVM classifier to classify the HEs and nonHEs. The experiment is based on the public diabetic retinopathy database DIARETDB1, we achieve a sensitivity of 91.1% and a specificity of 94.7%. The experimental results indicate that our method can conduct reliable detection of HEs.
