SEHDR: Single-Exposure HDR Novel View Synthesis via 3D Gaussian Bracketing

Yiyu Li, Haoyuan Wang, Ke Xu, Gerhard Petrus Hancke, Rynson W.H. Lau

ICCV 2025poster

This paper presents SeHDR, a novel high dynamic range 3D Gaussian Splatting (HDR-3DGS) approach for generating HDR novel views given multi-view LDR images. Unlike existing methods that typically require the multi-view LDR input images to be captured from different exposures, which are tedious to cap…

Color Shift Estimation-and-Correction for Image Enhancement

Yiyu Li, Ke Xu, Gerhard Petrus Hancke, Rynson W.H. Lau

CVPR 2024poster

Images captured under sub-optimal illumination conditions may contain both over- and under-exposures. We observe that over- and over-exposed regions display opposite color tone distribution shifts which may not be easily normalized in joint modeling as they usually do not have "normal-exposed" regio…
