High Dynamic Range Imaging Based on an Asymmetric Event-SVE Camera System
Pengju Sun, Banglei Guan, Jing Tao +4
High dynamic range (HDR) imaging under extreme illumination remains challenging for conventional cameras due to overexposure. Event cameras provide microsecond temporal resolution…
A DMD-Based Adaptive Modulation Method for High Dynamic Range Imaging in High-Glare Environments
Banglei Guan, Jing Tao, Liang Xu +5
Background The accuracy of photomechanics measurements critically relies on image quality,particularly under extreme illumination conditions such as welding arc monitoring and poli…
A Hardware-Algorithm Co-Designed Framework for HDR Imaging and Dehazing in Extreme Rocket Launch Environments
Jing Tao, Banglei Guan, Pengju Sun +3
Quantitative optical measurement of critical mechanical parameters -- such as plume flow fields, shock wave structures, and nozzle oscillations -- during rocket launch faces severe…
Perceptual Region-Driven Infrared-Visible Co-Fusion for Extreme Scene Enhancement
Jing Tao, Yonghong Zong, Banglei Guan +4
In photogrammetry, accurately fusing infrared (IR) and visible (VIS) spectra while preserving the geometric fidelity of visible features and incorporating thermal radiation is a si…
Event-based high temporal resolution measurement of shock wave motion field
Taihang Lei, Banglei Guan, Minzu Liang +4
Accurate measurement of shock wave motion parameters with high spatiotemporal resolution is essential for applications such as power field testing and damage assessment. However, s…
