Improved Nearest Neighbor Density-Based Clustering Techniques with Application to Hyperspectral Images

We consider the problem of density-based unsupervised classification in hyperspectral data. Our focus is especially on methods based on K nearest neighbors (KNN) graph. In this paper, we propose some improvements of recently published methods in this vein, namely GWENN (Graph WatershEd using Nearest…
