Researchers have developed MoCoTalk, a novel diffusion model designed for generating controllable talking head videos. This framework integrates four distinct conditional inputs: a reference image, facial keypoints, 3D facial models, and speech audio. To manage the interplay between these varied conditions, an adaptive router dynamically adjusts feature fusion based on the noise level and feature subspace. The model also introduces a mouth-augmented shading mesh for improved geometric consistency and a lip-sync loss for tighter audio-visual alignment, achieving state-of-the-art results. AI
