Features

• Neural Radiance Field Implementations - Implements a neural radiance field framework to represent scenes as continuous volumetric functions of density and color.
• Coordinate-Based Neural Representations - Encodes spatial information as continuous functions to achieve high-resolution 3D scene representations.
• Novel View Synthesis Engines - Generates high-fidelity images from camera perspectives not present in the original input data using volumetric calculations.
• Deformable Scenes - Implements a framework for reconstructing and rendering photorealistic 3D models of non-rigid, deforming objects.
• Volumetric Rendering Engines - Employs a volumetric rendering pipeline that samples along rays through a 3D volume to generate new viewpoints.
• Dynamic Radiance Fields - Utilizes volumetric deformation fields to model subjects that change shape while maintaining visual consistency.
• Volumetric Deformation Fields - Uses neural networks to map coordinates from a canonical space to a deformed state for modeling non-rigid motion.
• Coarse-to-Fine Optimization - Iteratively increases coordinate model resolution during training to ensure high-fidelity 3D reconstruction.
• Elastic Regularization - Constrains deformation fields to ensure the reconstructed object's movements remain smooth and physically realistic.
• Coordinate-Based - Refines volumetric deformations using coarse-to-fine optimization and elastic regularization for robust 3D model accuracy.
• Canonical Space Mappings - Maps 3D coordinates from a static reference pose to deformed states to represent motion over time.
• 3D Reconstruction Pipelines - Provides a pipeline that transforms photos and videos into high-fidelity 3D models.
