The near-real-time end-to-end evaluation of automatic target recognizers has been a reality in the laboratory environment for several years. Depending on the reliability of ground truth data, i.e., target location and sensor location in three dimensions and sensor pointing angle, field test evaluations could also be conducted at near real-time rates. End-to end evaluations, however, are inadequate for producing the quantity and quality of data needed for understanding both successes and failures of automatic recognition. The C2NVEO has developed a facility, called AUTOSPEC, for the expressed purpose of extracting intermediate data from processors. Once extracted, the data are stored in a relational database for subsequent analysis. The facility includes both the hardware and a number of software tools, developed at C2NVEO, designed to allow ready access to ground truth data, images, metrics, processor parameters, processor intermediate decisions, and processor final decisions. This paper presents the structure of the system and demonstrations of the tools developed.
