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.

Recovering high dynamic range (HDR) radiance from a single standard dynamic range (SDR) image is highly ill-posed. Extreme luminance variation and severe quantization in dark regions make accurate reconstruction challenging, often leading to visual artifacts and color distortions.

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.
