Coupled dictionary learning for unsupervised change detection between multi-sensor remote sensing images

no code implementations21 Jul 2018 Vinicius Ferraris, Nicolas Dobigeon, Yanna Cavalcanti, Thomas Oberlin, Marie Chabert

This paper addresses the problem of unsupervisedly detecting changes between two observed images acquired by sensors of different modalities with possibly different resolutions.

Robust fusion algorithms for unsupervised change detection between multi-band optical images - A comprehensive case study

no code implementations9 Apr 2018 Vinicius Ferraris, Nicolas Dobigeon, Marie Chabert

Unsupervised change detection techniques are generally constrained to two multi-band optical images acquired at different times through sensors sharing the same spatial and spectral resolution.

Robust Fusion of Multi-Band Images with Different Spatial and Spectral Resolutions for Change Detection

no code implementations20 Sep 2016 Vinicius Ferraris, Nicolas Dobigeon, Qi Wei, Marie Chabert

To alleviate these issues, classical change detection methods are applied after independent preprocessing steps (e. g., resampling) used to get the same spatial and spectral resolutions for the pair of observed images.
