Integration of Segmentation Techniques for Classification of Hyperspectral Images

Benediktsson, Jon Atli; Ghamisi, Pedram; Couceiro, Micael S.; Fauvel, Mathieu (IEEE, 2014)

A new spectral-spatial method for classification of hyperspectral images is introduced. The proposed approach is based on two segmentation methods, fractional-order Darwinian particle swarm optimization and mean shift segmentation. The output of these ...
Multilevel Image Segmentation Based on Fractional-Order Darwinian Particle Swarm Optimization

Benediktsson, Jon Atli; Ghamisi, Pedram; Martins, Fernando M. L.; Couceiro, Micael S. (IEEE, 2014)

Hyperspectral remote sensing images contain hundreds of data channels. Due to the high dimensionality of the hyperspectral data, it is difficult to design accurate and efficient image segmentation algorithms for such imagery. In this paper, a new ...
Spectral–Spatial Classification of Hyperspectral Images Based on Hidden Markov Random Fields

Benediktsson, Jon Atli; Ulfarsson, Magnus; Ghamisi, Pedram (IEEE, 2014)

Hyperspectral remote sensing technology allows one to acquire a sequence of possibly hundreds of contiguous spectral images from ultraviolet to infrared. Conventional spectral classifiers treat hyperspectral images as a list of spectral measurements ...
