Scene Albedo
Scene albedo, the inherent reflectivity of a surface independent of lighting, is a crucial element in computer vision and related fields, with research focusing on accurately recovering albedo information from images. Current efforts employ various techniques, including inverse rendering methods leveraging physics-based models and machine learning approaches like neural networks (e.g., NeRFs and diffusion models) to disentangle albedo from shading and lighting effects in both indoor and outdoor scenes. Accurate albedo estimation has significant implications for applications such as realistic 3D rendering, photogrammetry, planetary science, and even agricultural monitoring, enabling improved model creation, scene manipulation, and data analysis across diverse domains.
