Vid2Game: Controllable Characters Extracted from Real-World Videos

International Conference on Learning Representations (ICLR)

Abstract

We extract a controllable model from a video of a person performing a certain activity. The model generates novel image sequences of that person, according to user-defined control signals, typically marking the displacement of the moving
body. The generated video can have an arbitrary background, and effectively capture both the dynamics and appearance of the person.

The method is based on two networks. The first maps a current pose, and a single-instance control signal to the next pose. The second maps the current pose, the new pose, and a given background, to an output frame. Both networks include multiple novelties that enable high-quality performance. This is demonstrated on multiple characters extracted from various videos of dancers and athletes.
