Results of state-of-the-art unsupervised methods for FA image generation. The first to third and fourth to sixth rows show the transit phase to the late phase FA images, respectively, and the first column shows the original fundus structure image. The fundus structure and generated FA images have a size of 768 × 768 pixels. For a better comparison, we magnified the area enclosed in the red box. a Real FA image and results of b proposed method (LrGAN + HrGAN), c HrGAN, d method in [33], and e StarGAN
