This paper introduces a new system for real-time detection and classif
ication of arbitrarily scattered surface-laid mines from multispectral
imagery data of a minefield. The system consists of six channels whic
h use various neural-network structures for feature extraction, detect
ion, and classification of targets in six different optical bands rang
ing from near UV to near IR, A single-layer autoassociative network tr
ained using the recursive least square (RLS) learning rule was employe
d in each channel to perform feature extraction. Based upon the extrac
ted features, two different neural-network architectures were used and
their performance was compared against the standard maximum likelihoo
d (ML) classification scheme. The outputs of the detector/classifier n
etwork in all the channels were fused together in a final decision-mak
ing system. Two different final decision making schemes using the majo
rity voting and weighted combination based on consensual theory were c
onsidered. Simulations were performed on real data for six bands and o
n several images in order to account for the variations in size, shape
, and contrast of the targets and also the signal-to-clutter ratio, Th
e overall results showed the promise of the proposed system for detect
ion and classification of mines and minelike tagets.
