Poppy: Polarization-Based Plug-and-Play Guidance for Enhancing Monocular Normal Estimation

Refines surface normals from frozen RGB backbones using polarization measurements. Input/output offsets and reflectance decomposition are optimized through differentiable rendering to add physical constraints at inference time.
