The Hierarchical SEGmentation (HSEG) algorithm, which combines region object finding with region object clustering, has given good performances for multi- and hyperspectral image analysis. This technique produces at its output a hierarchical set of image segmentations. The automated selection of a single segmentation level is often necessary....

Recent advances in spectral-spatial classification of hyperspectral images are presented in this paper. Several techniques are investigated for combining both spatial and spectral information. Spatial information is extracted at the object (set of pixels) level rather than at the conventional pixel level. Mathematical morphology is first used...

In this paper, a new method for supervised hyperspectral data classification is proposed. In particular, the notion of stochastic Minimum Spanning Forest (MSF) is introduced. For a given hyperspectral image, a pixelwise classification is first performed. From this classification map, M marker maps are generated by randomly selecting pixels and...

The final version of this paper can be found in the IEEE Geoscience and Remote Sensing Magazine. The spectral signatures of the materials contained in hyperspectral images, also called endmembers (EM), can be significantly affected by variations in atmospheric, illumination or environmental conditions typically occurring within an image....

L'imagerie hyperspectrale (IH) est à l'heure actuelle encore trop peu considérée, pourtant ses spécificités en font un auxiliaire de poids pour le suivi des éléments du milieu urbain. Le projet HYEP a pour objectif de proposer un panel de méthodes et de traitements appliqués à l'imagerie hyperspectrale tout en comparant à celles d'autres...
