Single-image human relighting aims to relight a target human under new lighting conditions by decomposing the input image into albedo, shape and lighting. Although plausible relighting results can be achieved,
First, we recover the 3D geometry by optimizing a 775 Figure 1: We introduce SIRA, a method which, from a single image, reconstructs human head avatars with high fidelity geometry and factorized lights and surface materials. This information can then be used for relighting purposes. signed ...
The albedo estimated by SPAR3D has less baked-in lighting compared with SF3D and results in better relighting outcomes. Input Image Mesh Output Input Image Mesh Output Input Image Mesh Output Figure 10. Additional In-the-wild Results. We show additional results of SPAR3D on...
