Application: Animatable neural radiance fields from monocular rgb-d inputs (Patent ID: US20240104828A1)
The patent filed by Meta Platforms Inc. describes a method and system for generating a free-viewpoint rendering of a dynamic scene using an improved neural radiance fields (NeRF) based model. The method involves accessing image frames and depth information, generating latent representations based on point clouds and temporal relationships, and training the NeRF model for rendering. The system utilizes camera parameters and key frames to complete missing information and allows for rendering from novel viewpoints, even for unseen poses of objects in the scene.
The method further includes training the NeRF model by generating color and density values for rendering, comparing with ground-truth images, and updating the model based on the loss. Additionally, the system can handle human subjects in motion, capturing appearance details like facial and body characteristics. The method also involves user input for selecting desired novel viewpoints and utilizes neural networks for generating latent representations. The system can be implemented using processors and computer-readable storage media to access, generate, and train the NeRF model for free-viewpoint rendering of dynamic scenes.
