Moreover, a Progressive Negative Sample Selection mechanism (PNSS) is designed to mine more suitable negative samples for training, which can effectively promote detailed discrimination ability in the generative model and facilitate the generation of more fine-grained results. Extensive experiments on Oxford-102 and CUB datasets reveal that our MA-GAN significantly outperforms the state-of-the-art methods.Multipath and off-axis scattering are two of the primary mechanisms for ultrasound image degradation. To address their impact, we have
