US Patent:

7319796, Jan 15, 2008

Filed:

Sep 2, 2004

Appl. No.:

10/933123

Inventors:

Mary Sharp - Escondido CA, US

Assignee:

BAE Systems Information and Electronic Systems Integration Inc. - Nashua NH

International Classification:

G06K 9/36

US Classification:

382248

Abstract:

A method is disclosed herein for compressing spectral data corresponding to an image comprising a plurality of pixels. The method includes the step of creating a set of potential endmembers. A first plurality of the potential endmembers are identified as a first set of endmembers based upon their respective correlations with a first spectral signature of a first of the plurality of pixels. The first pixel is then represented as a combination of the first set of endmembers. Processing of the image preferably continues by identifying a second plurality of the potential endmembers as a second set of endmembers based upon their respective correlations with a second spectral signature of a second of the plurality of pixels. The second pixel is then represented as a combination of the second set of endmembers.
