Finite-event modulation transfer through forward-scattering media

How spatial structure is transferred through a forward-scattering medium depends jointly on pattern scale and propagation distance. Starting from photon exit displacements, we derive modulation transfer while retaining the number, depths, and projected angles of individual deflections, with event occurrences described...

Graph-Regularized Estimation for Inverse Problems in Computational Optical Imaging

Computational optical imaging reconstructs signals from limited and noisy measurements, leading to ill-posed inverse problems that require regularization. Graph regularization (GR) has shown promise for modeling complex spatial correlations, but its relationship to classical Total Variation (TV) regularization remains...

The Lift Spectrum: How Measurement-to-Space Adaptivity Shapes Robustness in Image-Free Single-Pixel Sensing

It is shown that removing image reconstruction relocates the central design problem to the lift: how 1D measurements become a 2D task representation, and measurement-to-space adaptivity organizes both the clean-to-noisy operating envelope and the failure a system encounters.
