Advances in technologies can make them competitive in areas where they were not. Nevertheless, most commercial
devices are designed with a particular application in mind. Attempting to use such a piece of equipment, notwithstanding
technological improvements, may provide a suboptimal solution. However, simple and inexpensive modifications can
sometimes be made allowing such a piece of equipment to have successful application is an area far removed from those
intended in its original design. This paper describes such a situation, where a commercial thermography product
designed for power line monitoring was modified to allow it to effectively function in a biometric application. Some of
the approaches taken here could be applied to other technologies and other applications that could profit the community.
Development of low-cost lightweight thermal sensors necessitates the re-evaluation of detection, classification and recognition criteria as applied to human performance with thermal imaging systems. The need exists to assess spatial and motion characteristics of man targets, rather than vehicle targets, and how these differing characteristics affect human perception and performance models. Higher order discriminations, such as determining activities and objects being carried are useful in determining range performance of specific sensors, and reflect the needs of the man-portable sensor user.
