Abstract

This paper will describe the development of a real time matched filtering technique for hyperspectral imagery. Advanced multispectral, or hyperspectral, camera systems can potentially be used to identify objects of interest on the basis of spectral characteristics. Matched filtering relies on there being a measurable difference between the spectrum of the target and that of background materials such as soil, vegetation, concrete and tarmac. If prior knowledge is available then the target can be found by numerically matching the two spectra. Tests have been carried out to evaluate the effectiveness of a technique that utilises a specific type of spectral matched filter. Some results from the tests will be presented that indicate how our technique is affected by changes in environmental and illumination conditions. Example detections of a number of unclassified objects will be presented.
