Architecture of proposed HrGAN with common encoders \({G}_{e}\), decoders \({G}_{d1}\), \({G}_{d2}\), and \({G}_{d3}\), and discriminators \({D}_{1}\), \({D}_{2}\), and \({D}_{3}\). \({G}_{e}\), \({G}_{d1}\), and \({D}_{1}\) are used for transit-phase FA image generation, while \({G}_{e}\), \({G}_{d2}\), and \({D}_{2}\) are used for recirculation-phase FA image generation, and \({G}_{e}\), \({G}_{d3}\), and \({D}_{3}\) are used for transit-phase FA image generation
