Hyperspectral data clustering based on density analysis ensemble

In this letter, we present a new hyperspectral data-clustering method, named density analysis ensemble, from a different perspective. Instead of distance-based metrics in traditional clustering methods, we use density analysis for hyperspectral data clustering. Moreover, in order to improve the performance, we use the random subspace ensemble method to formulate a set of clustering systems. The final results are retrieved through majority voting. Compared to the k-means method, the overall accuracies have been improved by 7.05% and 6.93% for the Salinas and Pavia University data sets, respectively.
