Measurement-Adaptive Light-Cone Transform for Robust Non-Line-of-Sight Imaging

Read the original on arXiv Computer Vision →

The paper introduces the Measurement-Adaptive Light-Cone Transform (MALCT), a physics-guided framework that maintains the efficient Fourier-domain inversion of traditional light-cone transform methods while adapting to real-world measurement noise and deviations in non-line-of-sight imaging. MALCT integrates an analytical response with a learned response via measurement-conditioned weighting and predicts a frequency-dependent regularization map within a unified variational formulation. An attention-enhanced spatio-temporal feature extraction module captures long-range temporal dependencies and local spatial correlations, enabling robust reconstruction under low-signal conditions and with reduced acquisition time, as demonstrated on synthetic data and real measurements from various NLOS systems.

STAR: Structure-aware Test-time Adaptation for diffusion-based light field Reconstruction

STAR (Structure-aware Test-time Adaptation for diffusion-based light field Reconstruction) addresses the ill‑posed problem of reconstructing a light field from limited, noisy focal stack measurements by adapting a pre‑trained diffusion prior to each test scene. The method freezes the diffusion model and trains three lightweight adapters that jointly capture within‑view spatial details, cross‑view angular dependencies, and disparity across views. Experiments show that STAR surpasses state‑of‑the‑art approaches in both two‑ and three‑focal‑sheet settings while achieving faster inference times than methods that update parameters at test time.

Learning Nonlinear Waveform Fusion Across Scales for Integrated Sensing and Communication

The paper proposes a method for learning nonlinear waveform fusion across scales to improve integrated sensing and communication (ISAC). By adaptively weighting temporal features and updating spectral components, the authors generate a waveform that maintains fixed total energy while combining image features with a deterministic frequency‑modulated reference. Experiments on 512 test images show that the learned waveforms reduce normalized localization error by 29.0 % and 27.0 % and increase mean peak SNR by 1.40 dB and 0.82 dB compared to baseline approaches.
