Methods and apparatus for adaptive foreground background analysis

A computer program product for processing a hyperspectral image, comprising:

• a first computer program portion adapted to receive the hyperspectral image;
• a second computer program portion adapted to spectrally unmix the hyperspectral image;
• a third computer program portion adapted to segment the hyperspectral image into a plurality of segments, each segment having at least one of similar spectral composition, similar textural composition, and similar variation;
• a fourth computer program portion adapted to spectrally unmix at least one of the segments;
• a fifth computer program portion adapted to create a clutter rejection filter for at least one segment and to use the clutter rejection filter to filter that segment;
• and
• a sixth computer program portion adapted to calculate an abundance of targets in at least one segment.

A sensor system for processing a scene, comprising:

• a sensor adapted to receive an hyperspectral image of the scene;
• a data reduction system operatively coupled to the sensor and including a processor and a memory device operatively coupled to the processor, wherein the data reduction system includes:
• a first portion adapted to receive the hyperspectral image of the scene from the sensor;
• a second portion adapted to spectrally unmix the hyperspectral image;
• a third portion adapted to segment the hyperspectral image into a plurality of segments, each segment having at least one of similar spectral composition, similar textural composition, and similar variation;
• a fourth portion adapted to spectrally unmix at least one of the segments;
• a fifth portion adapted to create a clutter rejection filter for the at least one segment and filter the at least one segment;
• and
• a sixth portion adapted to calculate an abundance of targets in the at least one segment.
