A Novel Adversarial Inference Framework for Video Prediction with Action Control
Zhihang Hu, Jason T. L. Wang · 2019
The ability of predicting future frames in video sequences, known as video prediction, is an appealing yet challenging task in computer vision. This task requires an in-depth representation of video sequences and a deep understanding of real-word causal rules. Existing approaches often result in blur predictions and lack the ability of action control. To tackle these problems, we propose a framework, called VPGAN, which employs an adversarial inference model and a cycle-consistency loss function to empower the framework to obtain more accurate predictions. In addition, we incorporate a conformal mapping network structure into VPGAN to enable action control for generating desirable future frames. In this way, VPGAN is able to produce fake videos of an object moving along a specific direction. Experimental results show that a combination of VPGAN with some pre-trained image segmentation models outperforms existing stochastic video prediction methods.
