In virtual reality and 3D modeling, constructing dynamic, high-fidelity digital human representations from limited data sources, such as single-view videos, presents a significant challenge. This task demands an intricate balance between achieving detailed and accurate digital representations and the computational efficiency required for real-time applications. Traditional methods often grapple with rendering speeds and model fidelity constraints due to their reliance on extensive training data and complex neural network architectures.

To address these challenges, researchers from ReLER, CCAI, and Zhejiang University have developed Human101, a groundbreaking framework that dramatically enhances the speed of training and rendering in virtual reality applications. This innovative approach is geared towards the rapid and efficient reconstruction of 3D digital humans, ensuring high fidelity in the models produced. The crux of Human101 lies in its unique integration of 3D Gaussian Splatting with advanced animation techniques. This integration facilitates the efficient processing of single-view video data to generate dynamic 3D human models.

Delving deeper into the methodology, Human101 leverages a novel Human-centric Forward Gaussian Animation method and a Canonical Human Initialization technique. The former represents a significant deviation from traditional inverse skinning used in NeRF-based pipelines. It avoids the exhaustive search for corresponding canonical points of the target pose points but directly deforms the canonical points into the observation space. This approach simplifies the deformation process and enhances the rendering speed. Meanwhile, the Canonical Human Initialization method significantly expedites the convergence of the model by initializing the original Gaussians more effectively.

The performance and results of Human101 are truly remarkable. The framework has demonstrated the capability to train 3D Gaussians in an astonishing 100 seconds, drastically reducing the time required compared to existing methodologies. Moreover, the rendering speeds surpass 100 FPS, a significant improvement that opens up new possibilities for real-time interactive applications and immersive virtual reality experiences. Such efficiency does not come at the cost of quality; the framework manages to maintain and, in many cases, surpass the visual fidelity of current methods.
