Abstract: Three-dimensional object representation and re-rendering systems and methods for producing a 3D representation of an object from 2D images including the object that enables object-centric rendering. A modular approach is used that optimizes a Neural Radiance Field (NeRF) model to estimate object geometry and refine camera parameters and, then, infer surface material properties and per-image lighting conditions that fit the 2D images.
