Given an action video, the goal is to generate the same action from an unseen viewpoint. Naturally, novel view video synthesis is more challenging than image synthesis. It requires the synthesis of a sequence of realistic frames with temporal coherency. Besides, transferring different actions to a novel target view requires awareness of action category and viewpoint change simultaneously. To address these challenges we propose a novel framework named Pose-guided Action Separable Generative Adversarial Net (PAS-GAN), which utilizes pose to alleviate the difficulty of this task. First, we propose a recurrent posetransformation module which transforms actions from the source view to the target view and generates novel view pose sequence in 2D coordinate space. Second, a welltransformed pose sequence enables us to separate the action and background in the target view. We employ a novel local-global spatial transformation modu...
