Fig. 4From: Recognition of eye diseases based on deep neural networks for transfer learning and improved D-S evidence theoryFundus image after RGB replacement. The left picture is the fundus image of the RBG channel, and the right picture is the fundus image of the BGR channel. The RGB coordinate system is a Cartesian coordinate system. Replacing the order of the channels will not change the structure of the image, but it will change the brightness and contrast of the image, so we use data augmentationBack to article page
