SVH-BD : Synthetic Vegetation Hyperspectral Benchmark Dataset for Emulation of Remote Sensing Images
Chedly Ben Azizi, Claire Guilloteau, Gilles Roussel +1
This dataset provides a large collection of 10,915 synthetic hyperspectral image cubes paired with pixel-level vegetation trait maps, designed to support research in radiative tran…
A Variational Latent-Space Framework for Uncertainty-Aware Spectral Image Emulation
Chedly Ben Azizi, Claire Guilloteau, Gilles Roussel +1
Synthetic spectral image generation is essential for remote sensing simulation and mission design, yet physically based radiative transfer models (RTMs) remain computationally expe…
Gaussian Compression Stream: Principle and Preliminary Results
Farouk Yahaya, Matthieu Puigt, Gilles Delmaire +1
Random projections became popular tools to process big data. In particular, when applied to Nonnegative Matrix Factorization (NMF), it was shown that structured random projections…
Faster-than-fast NMF using random projections and Nesterov iterations
Farouk Yahaya, Matthieu Puigt, Gilles Delmaire +1
Random projections have been recently implemented in Nonnegative Matrix Factorization (NMF) to speed-up the NMF computations, with a negligible loss of performance. In this paper,…
Post-Nonlinear Sparse Component Analysis Using Single-Source Zones and Functional Data Clustering
Matthieu Puigt, Anthony Griffin, Athanasios Mouchtaris
In this paper, we introduce a general extension of linear sparse component analysis (SCA) approaches to postnonlinear (PNL) mixtures. In particular, and contrary to the state-of-ar…
