Abstract:

We consider a novel problem of endmember detection in hyperspectral imagery where signal of frequency bands are probed sequentially. We propose an adaptive strategy in controlling the sensing order to maximize the normalized solid angle as a robustness measure of the problem geometry. This is based on efficiently identifying pure pixels t...More
