Emotalk3d
Overview :
EmoTalk3D is a research project focused on 3D virtual head synthesis that addresses issues of viewpoint consistency and inadequate emotional expression in traditional 3D head synthesis. By collecting multi-view videos, emotional annotations, and 3D geometries for each frame, this project proposes a novel approach to achieving controllable emotional synthesis of 3D heads through training on the EmoTalk3D dataset. It enhances lip synchronization and rendering quality, enabling the generation of 3D animations with a wide range of viewpoints and high rendering quality while capturing dynamic facial details, such as wrinkles and subtle expressions.
Target Users :
EmoTalk3D is designed for researchers and developers engaged in fields such as 3D animation, virtual reality, and augmented reality. It is suitable for scenarios that require the generation of highly realistic and emotionally expressive 3D virtual characters, such as film production, game development, and virtual assistants.
Use Cases
Using EmoTalk3D to generate emotionally expressive 3D characters in film production.
Game developers leveraging EmoTalk3D to create virtual characters with rich expressions.
Virtual assistants using EmoTalk3D technology for a more natural human-computer interaction experience.
Features
Emotion content separation encoder to parse content and emotional features from the input speech.
Speech-to-geometry network (S2GNet) to predict dynamic 3D point clouds.
Gaussian optimization and completion module to establish standard appearances.
Geometry-to-appearance network (G2ANet) for synthesizing facial appearances based on dynamic 3D point clouds.
Rendering module to render dynamic Gaussians into free-viewpoint animations.
EmoTalk3D dataset providing multi-view head data with emotional annotations.

Animate Anyone
Animate Anyone aims to generate character videos from static images driven by signals. Leveraging the power of diffusion models, we propose a novel framework tailored for character animation. To maintain consistency of complex appearance features present in the reference image, we design ReferenceNet to merge detailed features via spatial attention. To ensure controllability and continuity, we introduce an efficient pose guidance module to direct character movements and adopt an effective temporal modeling approach to ensure smooth cross-frame transitions between video frames. By extending the training data, our method can animate any character, achieving superior results in character animation compared to other image-to-video approaches. Moreover, we evaluate our method on benchmarks for fashion video and human dance synthesis, achieving state-of-the-art results.
