Hyperspectral Intrinsic Dimensionality Estimation With Nearest-Neighbor Distance Ratios


The first task to be performed in most hyperspectral unmixing chains is the estimation of the number of endmembers. Several techniques for this problem have already been proposed, but the class of fractal techniques for intrinsic dimensionality estimation is often overlooked. In this paper, we study an intrinsic dimensionality estimation technique based on… (More)
