Core Concepts
The author proposes a novel method, Say Anything with Any Style (SAAS), for generating stylized talking head videos by extracting speaking styles in a discrete manner and utilizing a multi-task VQ-VAE model.
Abstract
The content introduces the SAAS framework for generating stylized talking head videos with accurate lip synchronization and diverse head poses. By leveraging a style codebook, HyperStyle, and pose generator, the method surpasses state-of-the-art approaches in terms of image quality and performance metrics.
The approach involves extracting speaking styles through a generative model with learned style codebooks, enhancing precision and robustness. A residual architecture is used to predict mouth shapes based on driving audio while transferring speaking styles effectively.
Experiments demonstrate superior results in both audio-driven and video-driven setups, showcasing the effectiveness of the proposed SAAS framework. The content also includes comparisons with existing methods, user studies, ablation studies, and detailed explanations of the methodology.
Stats
Experiments demonstrate that our approach surpasses state-of-the-art methods in terms of both lip-synchronization and stylized expression.
Our method achieves the best performance in terms of all metrics on MEAD dataset and most metrics on HDTF dataset.
SAAS-V significantly exceeds SOTAs among all metrics on both datasets.
Quotes
"The robustness of subsequent modules in our framework is significantly enhanced since the extracted style is dragged closer to the seen style of training dataset."
"Our contributions are summarized as follows: We propose Say Anything with Any Style model (i.e., SAAS) to generate accurate lip motion synchronized with audio."
"Extensive experiments demonstrate the superiority of our method compared to state-of-the-arts (SOTAs)."
