A novel graph-based approach for segmenting hyperspectral images which guarantees similarity of pixels (spectra) inside each segment.

A study was undertaken to find a divergence measure that can with some level of accuracy identify whether a pair of samples are similar or dissimilar. The algorithm then creates a segmentation such that all pixels inside the segment are similar/uniform. Following this we show that the new technique improves on the segmentation performance of existing algorithms.
