BRDF estimation

BRDF estimation is a key task in computer vision that aims to accurately estimate the Bidirectional Reflectance Distribution Function of a surface through image analysis and modeling techniques. The goal of this task is to recover the reflective properties of the surface under various lighting conditions, enabling more realistic material rendering and scene reconstruction. BRDF estimation holds significant application value in fields such as virtual reality, augmented reality, film special effects, and 3D modeling, as it can greatly enhance the realism and immersion of visual effects.
