Minimates
Overview :
MiniMates is a lightweight image-driven algorithm for digital humans that can run in real-time on ordinary computers, supporting both voice and expression-driven modes. It operates 10 to 100 times faster than algorithms like liveportrait, EchoMimic, and MuseTalk, allowing users to customize their AI companions with minimal resource consumption. The main advantages of this technology include a rapid experience, personalized customization, and terminal embedding capability, eliminating the need for Python and CUDA dependencies. MiniMates follows the MIT license and is suitable for applications requiring fast and efficient facial animation and voice synthesis.
Target Users :
The target audience includes game developers, animators, VR/AR content creators, and anyone who needs to quickly implement digital human animations. The rapid experience and customization capabilities of MiniMates make it an ideal choice for these users, especially when resources are limited.
Use Cases
Game developers use MiniMates to quickly generate realistic facial expressions and voices for game characters.
Animators leverage MiniMates to create virtual hosts for real-time streaming and interaction.
Educators utilize MiniMates to produce teaching materials that enhance student engagement through AI companions.
Features
Rapid experience: Real-time expression and voice driving of digital humans using just the CPU without the need for a dedicated graphics card.
Personalized customization: Supports one-shot single image driving; a minimum of just one image is required to drive a digital human.
Terminal embedding: Can run on various devices without relying on Python and CUDA.
Supports voice-driven and expression-driven modes: Digital humans can be driven in real-time based on voice and facial expressions.
Real-time camera expression driving: Achieves real-time expression driving using mediapipe for ARKit expression capture.
Various driving modes: Supports rotation, audio, and hybrid driving modes.
Cross-platform support: Compatible with multiple operating systems, including Windows, Mac, and Linux.
How to Use
1. Obtain the pre-trained model and place it in the checkpoint folder within your project directory.
2. Create a Python environment and install necessary dependencies, such as torch and libraries listed in requirements.txt.
3. If portrait extraction is needed, use the provided matting.py script to process images.
4. Conduct quick tests using the interface_face.py script with a camera to observe the character's movement following head motions.
5. Generate expression templates from videos using generate_move_template.py.
6. Use the interface_audio.py script to generate videos with characters synced to audio files and expression templates.
7. Adjust algorithm parameters as needed to optimize the performance of digital humans.
