Multi‐Spectral Gaussian Splatting with Neural Color Representation

Computer Graphics Forum, EarlyView.
Abstract 3D Gaussian Splatting (3DGS) [KKLD23] has transformed novel‐view synthesis from RGB images, yet remains restricted to the visible spectrum. Many applications, including agricultural monitoring, rely on multi‐spectral imaging, where spectral camera alignment and scalability pose major challenges.

Tropical leaf phenology as a thermoregulation trait: how changes in crown structure modulate thermal dynamics for two dominant Hawaiian trees

New Phytologist, EarlyView.
Study site and focal species. Summary Canopy and leaf temperatures often diverge from air temperature, influencing photosynthesis, water loss, and heat stress. While leaf traits are known to affect heat exchange, how changes in crown structure interact with environmental drivers to regulate canopy thermal dynamics is poorly understood, particularly in ...

Sparsity‐Driven Source Localization in Tomographic Sensing Applications

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Hyperspectral standoff detection systems such as Focal Plane Array (FPA) Fourier Transform Infrared (FTIR) spectrometers provide high spatial resolution in detecting airborne chemical contaminants that are invisible to the human eye but potentially hazardous. When two such systems are operated simultaneously with a suitable opening angle, they
