PolarAnything: Diffusion-based Polarimetric Image Synthesis

Kailong Zhang, Youwei Lyu, Heng Guo, Si Li, Zhanyu Ma, Boxin Shi

ICCV 2025poster

Polarization images facilitate image enhancement and 3D reconstruction tasks, but the limited accessibility of polarization cameras hinders their broader application. This gap drives the need for synthesizing photorealistic polarization images. The existing polarization simulator Mitsuba relies on a…

SfPUEL: Shape from Polarization under Unknown Environment Light

Youwei Lyu, Heng Guo, Kailong Zhang, Si Li, Boxin Shi

NeurIPS 2024poster

Shape from polarization (SfP) benefits from advancements like polarization cameras for single-shot normal estimation, but its performance heavily relies on light conditions. This paper proposes SfPUEL, an end-to-end SfP method to jointly estimate surface normal and material under unknown environment…
