Non-line-of-sight imaging with arbitrary relay surface geometries via 3D Gaussian Transient Rendering
Yi Wang, Ziyu Zhan, Yuran Wang +5
Imaging objects hidden outside the direct line of sight expands the effective field of view and is critical for applications such as autonomous driving and robotic perception. Desp…
Fast and Memory-efficient Non-line-of-sight Imaging with Quasi-Fresnel Transform
Yijun Wei, Jianyu Wang, Leping Xiao +3
Non-line-of-sight (NLOS) imaging seeks to reconstruct hidden objects by analyzing reflections from intermediary surfaces. Existing methods typically model both the measurement data…
Neumann Series-based Neural Operator for Solving Inverse Medium Problem
Ziyang Liu, Fukai Chen, Junqing Chen +2
The inverse medium problem, inherently ill-posed and nonlinear, presents significant computational challenges. This study introduces a novel approach by integrating a Neumann serie…
Traceability of Water Pollution: An Inversion Scheme Via Dynamic Complex Geometrical Optics Solutions
Lingyun Qiu, Zhongjing Wang, Hui Yu +1
We investigate the identification of the time-dependent source term in the diffusion equation using boundary measurements. This facilitates tracing back the origins of environmenta…
