SEMI-AUTOMATIC TARGET RECOGNITION DEVICE
Abstract
A summary of the work to develop techniques for machine recognition of targets on aerial reconnaissance photographs and to construct a device which demonstrates the feasibility of these techniques is presented. The results of the study ph this procurement led to the choice of a parametric approach to target recognition and the decision to employ both electronic and electro-optical means to extract the necessary parameters. The Semi-Automatic Target Recognition Device (SATRD) developed on this contract utilizes a flying spot scanner with a rotating raster to extract parameters related to target texture and a two-channel area-matching optical system to detect specific shapes. An automatic learning and recognition computer program was utilized to evaluate the electronic parameter data extracted from a set of 150 aerial photo graphs, consisting of 15 samples of each of 10 strategic target classes. Due to a lack of sufficient light output from the scanner, optical parameters were not extracted from the set of aerial photographs. However, results are reported on a series of experiments that indicate the feasibility of area matching for the detection of specific shapes-with special applicability to the recognition of tactical targets.
