Deep learning for predicting refractive error from multiple photorefraction images
BioMedical Engineering OnLine, 2022 Background Refractive error detection is a significant factor in preventing the development of myopia. To improve the efficiency and accuracy of refractive error detection, a refractive error detection network (REDNet) is proposed that combines the ...
