Relevance Spectroscopy Example -Hydice "TERRAIN" image

These images illustrate the application of relevance spectroscopy to the sample 'TERRAIN' hyperspectral image available from http://www.agc.army.mil/Hypercube/pub/TERRAIN.zip.

To the right is a 3 band 'true color' selection from that 225 band image showing training regions for the five classes of interest.
False color image based on optimum 3 band combination derived using training regions shown in 'true color' image above.

Band selection required approximately 1 minute on PC from the time training regions were selected.
WAY-2C interpretation of 3 band combination image derived in previous step. The interpretation required approximately 1 second on a PC after optimum bands had been selected.
