Context-aware Talking Face Video Generation
This addresses the need for more natural and context-aware video generation in applications like virtual meetings or entertainment, though it is incremental as it builds on existing talking face generation methods.
The paper tackles the problem of generating talking face videos in multi-person interaction scenarios by incorporating contextual information, resulting in improved audio-video synchronization, video fidelity, and frame consistency compared to baselines.
In this paper, we consider a novel and practical case for talking face video generation. Specifically, we focus on the scenarios involving multi-people interactions, where the talking context, such as audience or surroundings, is present. In these situations, the video generation should take the context into consideration in order to generate video content naturally aligned with driving audios and spatially coherent to the context. To achieve this, we provide a two-stage and cross-modal controllable video generation pipeline, taking facial landmarks as an explicit and compact control signal to bridge the driving audio, talking context and generated videos. Inside this pipeline, we devise a 3D video diffusion model, allowing for efficient contort of both spatial conditions (landmarks and context video), as well as audio condition for temporally coherent generation. The experimental results verify the advantage of the proposed method over other baselines in terms of audio-video synchronization, video fidelity and frame consistency.
