Semi-supervised Classification of Multi/Hyperspectral Images Based on Cluster Ensemble
A semi-supervised, cluster-ensemble based method for the classification of multi/hyperspectral images is presented.Spectral clustering is a graph theory based clustering algorithm taking similarity as the basis, and has become increasingly popular in recent years.It can deal with arbitrary distribution of dataset but with a drawback for being sensitive to the scaling parameters.Cluster ensemble techniques are effective in improving both the robustness and the stability of the single clustering algorithm.Cluster ensemble also has a character of good robustness and generalization ability.The processing method in this paper utilizes the merits of cluster ensemble and develops a consensus function based spectral clustering algorthm.The clustering components are generated by spectral clustering.The affinity matrix is generated by computing the SAM between different datapoints.The Nystrm method is used to to speed up the classification process.Thus semi-supervised classification to multi/hyperspectral remote sensed data is completed.Experiments show that the method presented here has an excellent classificaation result for both multispectral and hyperspectral remote sensed dataset.
