Avatarpose
Overview :
AvatarPose is a method for estimating the 3D poses and shapes of multiple closely interacting individuals from sparse multi-view videos. The technology reconstructs each person's personalized implicit neural avatar and uses it as a prior to refine poses through color and silhouette rendering loss, significantly enhancing the robustness and accuracy of 3D pose estimation in closely interactive scenarios.
Target Users :
The target audience includes researchers and developers in the field of computer vision, particularly those focused on 3D human pose estimation and motion capture technologies. This technology helps them capture and analyze human motions more accurately, making it suitable for various applications such as virtual reality, augmented reality, animation production, and sports analysis.
Use Cases
Simulating real human movements in virtual reality environments.
Precise capturing and reproduction of character movements in animated films.
Analyzing athletes' movements in sports training to improve performance.
Features
Utilizes personalized implicit neural avatars as priors to improve pose estimation robustness and accuracy.
Efficiently reconstructs avatars from multi-view videos using layered volumetric rendering techniques.
Combines RGB and silhouette rendering loss to enhance 3D pose optimization.
Introduces collision loss to prevent inter-character penetration.
Alternates between avatar learning and pose optimization to achieve complete and accurate 3D human poses.
Demonstrates state-of-the-art performance across multiple public datasets.
How to Use
1. Prepare sparse multi-view video input.
2. Utilize the AvatarPose model to reconstruct personalized avatars for individuals in the video.
3. Employ the reconstructed avatars as priors and refine poses using color and silhouette rendering loss.
4. Introduce collision loss to address inter-character penetration issues.
5. Alternate between avatar learning and pose optimization until satisfactory 3D pose estimation results are achieved.
6. Validate model performance on public datasets to ensure accuracy and robustness.
