Abstract

We present models and algorithms for recognizing 3D objects in airborne 0.4-2.5 micron hyperspectral images acquired under unknown conditions. Objects of interest exhibit complex geometries with surfaces of different materials. The DIRSIG image generation software is used to build spatial/spectral surfaces of different materials. The DIRSIG image generation software is used to build spatial/spectral subspace models for the objects that capture a range of atmospheric and illumination conditions and viewing geometries. Since we consider scales for which multiple materials will mix in a pixel, the object subspace models also account for spectral mixing. An important aspect of the work is the use of methods for partitioning object subspaces to optimize performance. The new algorithms have been evaluated using hyperspectral data that has been synthesized for a range of conditions.
