PSAT-GAN: Efficient Adversarial Attacks Against Holistic Scene Understanding

IEEE Transactions on Image Processing, 2021
Recent advances in deep neural networks (DNNs) have facilitated high-end applications, including holistic scene understanding (HSU), in which many tasks run in parallel with the same visual input. Following this trend, various methods have been proposed to use DNNs to perform multiple vision tasks.
