GravCal: Single-Image Calibration of IMU Gravity Priors with Per-Sample Confidence
Haichao Zhu, Qian Zhang
Gravity estimation is fundamental to visual-inertial perception, augmented reality, and robotics, yet gravity priors from IMUs are often unreliable under linear acceleration, vibra…
Illumination-Invariant Active Camera Relocalization for Fine-Grained Change Detection in the Wild
Nan Li, Wei Feng, Qian Zhang
Active camera relocalization (ACR) is a new problem in computer vision that significantly reduces the false alarm caused by image distortions due to camera pose misalignment in fin…
Adversarial Relighting Against Face Recognition
Qian Zhang, Qing Guo, Ruijun Gao +3
Deep face recognition (FR) has achieved significantly high accuracy on several challenging datasets and fosters successful real-world applications, even showing high robustness to…
Active Lighting Recurrence by Parallel Lighting Analogy for Fine-Grained Change Detection
Qian Zhang, Wei Feng, Liang Wan +3
This paper studies a new problem, namely active lighting recurrence (ALR) that physically relocalizes a light source to reproduce the lighting condition from single reference image…
