Playable Environments: Video Manipulation in Space and Time

arXiv 2022 32.2 method, system

TLDR

A framework for interactive video generation and manipulation from a single image, enabling 3D object movement and camera control via unsupervised actions.

Reasoning

Strengths include a novel representation for interactive video manipulation and unsupervised action learning; weaknesses are reliance on estimated camera parameters and 2D locations, and lack of explicit evaluation on real-world dynamics or generalization.
