Abstract

A shape-based algorithm, designated SPOT, is applied to the output of ARL’s, contrast-like feature based, FLIR anomaly target detector in an effort to improve clutter rejection. The shape-based algorithm uses a spatial symmetry operator that discriminates man-made structures in imagery. The method uses no predetermined templates or filters, which would be range and/or aspect dependent, but rather generates templates on-the-fly from the input data. Results explore the application of one such symmetry operator, and present a comparative analysis of target detection performance, based on ROC curves and detection histograms.
