High-Speed Full-Color HDR Imaging via Unwrapping Modulo-Encoded Spike Streams
Chu Zhou, Siqi Yang, Kailong Zhang +4
Conventional RGB-based high dynamic range (HDR) imaging faces a fundamental trade-off between motion artifacts in multi-exposure captures and irreversible information loss in singl…
PolGS++: Physically-Guided Polarimetric Gaussian Splatting for Fast Reflective Surface Reconstruction
Yufei Han, Chu Zhou, Youwei Lyu +6
Accurate reconstruction of reflective surfaces remains a fundamental challenge in computer vision, with broad applications in real-time virtual reality and digital content creation…
Near-Light Color Photometric Stereo for Mono-Chromatic Non-Lambertian Surfaces
Zonglin Li, Jieji Ren, Shuangfan Zhou +6
Color photometric stereo enables single-shot surface reconstruction, extending conventional photometric stereo that requires multiple images of a static scene under varying illumin…
RotatedMVPS: Multi-view Photometric Stereo with Rotated Natural Light
Songyun Yang, Yufei Han, Jilong Zhang +4
Multiview photometric stereo (MVPS) seeks to recover high-fidelity surface shapes and reflectances from images captured under varying views and illuminations. However, existing MVP…
SymmeTac: Symmetric Color LED Driven Efficient Photometric Stereo Reconstruction Methods for Camera-based Tactile Sensors
Jieji Ren, Heng Guo, Zaiyan Yang +6
Camera-based tactile sensors can provide high-density surface geometry and force information for robots in the interaction process with the target. However, most existing methods c…
