Several simple, low-cost algorithms have been explored for use in the enhancement of imagery produced by uncooled focal plane arrays (UFPA). These algorithms address the main problems that UFPA-produced imagery typically demonstrate. In addition to enhancing UFPA-produced imagery, all these algorithms are simple and allow for inexpensive hardware implementation.
