Optimization on the manifold of multiple homographies [PDF]

2009 IEEE 12th International Conference on Computer Vision Workshops, ICCV Workshops, 2009
It has long been known that the set of homographies for several planes in two images, as well as the homologies of a pair of planes in several images, all lie in a 4-dimensional subspace. It has also been shown that enforcing these constraints improves the accuracy of the homography estimation process. In this paper we show that the constraints on such

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.

From Observed Damage to Executable Repair Quantities: The RELA Repair Module

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Postearthquake workflows currently support three distinct classes of decisions: safety clearance through rapid tagging, portfolio‐level economic damage estimation through probabilistic loss models, and field inspections based on locally defined survey forms, which may subsequently trigger project‐specific strengthening through retrofit design. However,

Nonlinear Kinematic Depth Inversion Coupled With a Spectral Wave Model

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract We present a bidirectional coupling between a nonlinear kinematic depth inversion method and a phase‐averaged spectral wave model to evaluate the influence of wave nonlinearity over gently sloping nearshore bathymetry. Time‐resolved wave imagery provides spatially varying frequency–wavenumber fields, whereas the simulated significant wave ...
