Until recently the development of FLIR Automatic Target Recognizers (ATRs) has been constrained by several pitfalls, including an inadequate specification and choice of training data. Moreover, the best data bases in the world have proven to be of little value when surrogate features are extracted without scientific cunning. Ad hoc selection of the classifier is the final pitfall.
