Disentangling Content and Motion for Text-Based Neural Video Manipulation
This work addresses the challenge of text-based video manipulation for computer vision applications, representing an incremental improvement over prior methods.
The paper tackles the problem of manipulating videos with natural language to alter object appearances, introducing DiCoMoGAN which disentangles content and motion for controllable semantic edits, and it significantly outperforms existing frame-based methods in producing temporally coherent and semantically meaningful results.
Giving machines the ability to imagine possible new objects or scenes from linguistic descriptions and produce their realistic renderings is arguably one of the most challenging problems in computer vision. Recent advances in deep generative models have led to new approaches that give promising results towards this goal. In this paper, we introduce a new method called DiCoMoGAN for manipulating videos with natural language, aiming to perform local and semantic edits on a video clip to alter the appearances of an object of interest. Our GAN architecture allows for better utilization of multiple observations by disentangling content and motion to enable controllable semantic edits. To this end, we introduce two tightly coupled networks: (i) a representation network for constructing a concise understanding of motion dynamics and temporally invariant content, and (ii) a translation network that exploits the extracted latent content representation to actuate the manipulation according to the target description. Our qualitative and quantitative evaluations demonstrate that DiCoMoGAN significantly outperforms existing frame-based methods, producing temporally coherent and semantically more meaningful results.
