Implicit Neural Representations (INRs) have emerged as a compelling paradigm for modeling multidimensional signals by mapping continuous coordinates to signal values. However, Multi-Layer Perceptrons (MLP)-based INRs inherently suffer from spectral bias, which favors low-frequency components and suppresses the reconstr...
Dual-spectral measurement instruments integrate complementary thermal radiation and textural information, thereby alleviating the information acquisition limitations of single-modality sensors. Due to detector manufacturing constraints and hardware cost, the infrared sensors usually provide lower spatial sampling rates...

A fast implicit light field representation based on geometric decomposition and multi-resolution low-rank features that achieves competitive reconstruction quality while providing a better trade-off among model parameters, training time, and inference efficiency is proposed.

A physics-driven iterative framework rooted in the polychromatic Polyquant attenuation model is proposed, which decouples scatter and beam hardening artifacts by establishing an optimization loop between scatter estimation and relative electron density (RED) reconstruction.
