Variational Mode Decomposition for estimating critical reflected internal wave in stratified fluid
Ernesto Horne, Jeremy Schmitt, Nelly Pustelnik +2
The shear resulting from internal wave reflections can play a crucial role in the transport and resuspension of sediments in oceanic conditions. In particular, when these waves und…
Adaptive Hamiltonian Variational Integrators and Symplectic Accelerated Optimization
Valentin Duruisseaux, Jeremy Schmitt, Melvin Leok
It is well known that symplectic integrators lose their near energy preservation properties when variable step sizes are used. The most common approach to combine adaptive step siz…
Lagrangian and Hamiltonian Taylor Variational Integrators
Jeremy Schmitt, Tatiana Shingel, Melvin Leok
In this paper, we present a variational integrator that is based on an approximation of the Euler--Lagrange boundary-value problem via Taylor's method. This can viewed as a special…
Properties of Hamiltonian Variational Integrators
Jeremy M. Schmitt, Melvin Leok
Discrete Hamiltonian variational integrators are derived from Type II and Type III generating functions for symplectic maps, and in this paper we establish a variational error anal…
2-D Prony-Huang Transform: A New Tool for 2-D Spectral Analysis
Jérémy Schmitt, Nelly Pustelnik, Pierre Borgnat +2
This work proposes an extension of the 1-D Hilbert Huang transform for the analysis of images. The proposed method consists in (i) adaptively decomposing an image into oscillating…
Multichannel Poisson denoising and deconvolution on the sphere : Application to the Fermi Gamma Ray Space Telescope
Jérémy Schmitt, Jean-Luc Starck, Jean-Marc Casandjian +2
A multiscale representation-based denoising method for spherical data contaminated with Poisson noise, the multiscale variance stabilizing transform on the sphere (MS-VSTS), has be…
Poisson Denoising on the Sphere: Application to the Fermi Gamma Ray Space Telescope
J. Schmitt, J. L. Starck, J. M. Casandjian +2
The Large Area Telescope (LAT), the main instrument of the Fermi Gamma-Ray Space Telescope, detects high energy gamma rays with energies from 20 MeV to more than 300 GeV. The two m…
