Operator Performance in Pattern Matching as a Function of Reference MaterialStructure

摘要

This report describes the results of two experiments that examine operatoraccuracies and response times to recognize matches and mismatches between line drawings and photographs. The line drawings used in the experiments were generated by the procedures used in the Land-Attack Multi-sensor Correlation (LMC), which is a targeting system under development at China Lake. The experiments varied the number of pixels in the line drawings, the manner in which the pixels were varied, and the kind of premission experience the operators had with the imagery. In addition, the performance results were used to demonstrate an approach that might be used to set a criterion score for calling out a match by the LMC.
