Paper Abstract
Target detection is the act of isolating objects of interest from the surrounding clutter, generally using some form of
test to include objects in the found class. However, the method of determining the threshold is overlooked relying on
manual determination either through empirical observation or guesswork. The question remains: how does an
analyst identify the detection threshold that will produce the optimum results? This work proposes the concept of a
target detection sweet spot where the missed detection probability curve crosses the false detection curve; this
represents the point at which missed detects are traded for false detects in order to effect positive or negative
changes in the detection probability. ROC curves are used to characterize detection probabilities and false alarm
rates based on empirically derived data. It identifies the relationship between the empirically derived results and the
first moment statistic of the histogram of the pixel target value data and then proposes a new method of applying the
histogram results in an automated fashion to predict the target detection sweet spot at which to begin automated
target detection.
