摘要
Diabetic retinopathy causes various abnormality in retinal vessels. In addition, Detection and identification of vessel anomaly are challenging due to nature of complexity in retinal vessels. UW-OCTA provides high-resolution image of those vessels to diagnose lesions of vessels. However, the image suffers noise of image. We here propose a deep learning-based multi-tasking systems for DR in UW-OCTA images to deal with diagnosis and checking image quality. We segment three kinds of retinal lesions with data-adaptive U-Net architectures, i.e. nnUNet, grading images on image quality and DR severity grading by soft-voting outputs of fine-tuned multiple convolutional neural networks. For three tasks, we achieve Dice similarity coefficient of 0.5292, quadratic weighted Kappa of 0.7246, and 0.7157 for segmentation, image quality assessment, and grading DR for test set of DRAC2022 challenge. The performance of our proposed approach demonstrates that task-adaptive U-Net planning and soft ensemble of CNNs can provide enhancement of the performance of single baseline models for diagnosis and screening of UW-OCTA images.
