Development of a new spectral library classifier for airborne hyperspectral images on heterogeneous environments

, 2011
The classification of hyperspectral images on heterogeneous environments without prior knowledge about the study area is a challenging task. Finding potential pure spectral signatures or endmembers (EM) of the various surface materials within an image is

Spatial analysis for colon biopsy classification from hyperspectral imagery [PDF]

, 2008
Automatic classification of histology images, the objective of our research, is aimed at supporting the pathologists in their diagnosis. In this paper, we present a comparative study between 3D spectral/spatial analysis (SSA) and 2D spatial analysis (SA ...

Hyperspectral Image Resolution Enhancement Based on Spectral Unmixing and Information Fusion

, 2011
Hyperspectral imaging sensors exibit high spectral resolution, but normally low spatial resolution. This leads to spectral signatures of pixels originating from different object types. Such pixels are called mixed pixels.
