🎏 Abstract

Achieving disentangled control over multiple facial motions and accommodating diverse input modalities greatly enhances the application and entertainment of the talking head generation. This necessitates a deep exploration of the decoupling space for facial features, ensuring that they a) operate independently without mutual interference and b) can be preserved to share with different modal inputs—both aspects often neglected in existing methods. To address this gap, this paper proposes a novel Efficient Disentanglement framework for Talking head generation (EDTalk). Our framework enables individual manipulation of mouth shape, head pose, and emotional expression, conditioned on both video and audio inputs. Specifically, we employ three lightweight modules to decompose the facial dynamics into three distinct latent spaces representing mouth, pose, and expression, respectively. Each space is characterized by a set of learnable bases whose linear combinations define specific motions. To ensure independence and accelerate training, we enforce orthogonality among bases and devise an efficient training strategy to allocate motion responsibilities to each space without relying on external knowledge. The learned bases are then stored in corresponding banks, enabling shared visual priors with audio input. Furthermore, considering the properties of each space, we propose Audio-to-Motion module for audio-driven talking head synthesis. Experiments are conducted to demonstrate the effectiveness of EDTalk.

🎮 Installation

We train and test based on Python 3.8 and Pytorch. To install the dependencies run:

git clone https://github.com/tanshuai0219/EDTalk.git
cd EDTalk

Install dependency

conda create -n EDTalk python=3.8
conda activate EDTalk

python packages

pip install -r requirements.txt

🎬 Quick Start

Download the checkpoints and put them into ./ckpts.

Run the demo in audio-driven setting (EDTalk-A):

For user-friendliness, we extracted the weights of eight common sentiments in the expression base. one can directly specify the sentiment to generate emotional talking face videos (recommended)

python demo_EDTalk_A_using_predefined_exp_weights.py --source_path path/to/image --audio_driving_path path/to/audio --pose_driving_path path/to/pose --exp_type type/of/expression --save_path path/to/save

Or you can input an expression reference (image/video) to indicate expression.

python demo_EDTalk_A.py --source_path path/to/image --audio_driving_path path/to/audio --pose_driving_path path/to/pose --exp_driving_path path/to/expression --save_path path/to/save

The result will be stored in save_path.

Source_path and videos used must be first cropped using scripts crop_image.py and crop_video.py

For images where faces only make up a small portion of the image, we recommend using the crop_image2.py to crop image.

Run the demo in video-driven setting (EDTalk-V):

python demo_EDTalk_V.py --source_path path/to/image --lip_driving_path path/to/lip --audio_driving_path path/to/audio --pose_driving_path path/to/pose --exp_driving_path path/to/expression --save_path path/to/save

The result will be stored in save_path.
