Roll invariant target detection based on PolSAR clutter models
Based on the Kennaugh-Huynen decomposition, the Target Scattering Vector Model (TSVM) allows to extract four rollinvariant parameters. Those parameters are necessary for an unambi...

Spatial preprocessing for endmember extraction using unsupervised clustering and orthogonal subspace projection concepts
In this paper, we develop a new spatial preprocessing strategy which can be applied prior to a spectral-based endmember extraction process for unmixing of hyperspectral data. Our ...
