Abstract :
A preliminary detection algorithm and wavelet difference reduction (WDR) with region of interest priority compression are combined to successful identify small targets in multispectral imagery. The technique addresses not only detection capability, but also practical unmanned aerial vehicle (UAV) implementation restrictions. The restrictions that are overcome are small processing capability and variable bandwidth datalinks.
