A High-accuracy Event-based Underwater SLAM System
Yifan Peng, Qihang Liu, Haoying Li +3
While event cameras offer immense potential for underwater SLAM, existing Time Surface (TS)-based methods prove highly unreliable when deployed underwater. Fluctuating camera veloc…
Supervisory Measurement-Guided Noise Covariance Estimation
Haoying Li, Yifan Peng, Xinghan Li +1
Reliable state estimation hinges on accurate specification of sensor noise covariances, which weigh heterogeneous measurements. In practice, these covariances are difficult to iden…
Supervisory Measurement-Guided Noise Covariance Estimation: Discussing Forward and Reverse Differentiation
Haoying Li, Yifan Peng, Yuchi Wu +1
Reliable state estimation depends on accurately modeled noise covariances, which are difficult to determine in practice. This paper formulates the noise covariance estimation as a…
Two-Stage Decoupling Framework for Variable-Length Glaucoma Prognosis
Yiran Song, Yikai Zhang, Silvia Orengo-Nania +5
Glaucoma is one of the leading causes of irreversible blindness worldwide. Glaucoma prognosis is essential for identifying at-risk patients and enabling timely intervention to prev…
AquaticVision: Benchmarking Visual SLAM in Underwater Environment with Events and Frames
Yifan Peng, Yuze Hong, Ziyang Hong +2
Many underwater applications, such as offshore asset inspections, rely on visual inspection and detailed 3D reconstruction. Recent advancements in underwater visual SLAM systems fo…
