The problem of correlating images with random contrast reversals is considered. This problem arises mainly in registration of Multi-Sensor or Multi-Temporal imagery for applications such as Missile Guidance, Map Matching, Map Differencing and alike. A new approach to the registration performance analysis is presented, which enables the choice of both an appropriate processor configuration and optimal parameters - so as to maximize some common performance measures. The mathematical model, developed to depict the problem, not only leads to the formal solution but also provides insight into the physical relationships involved. A hybrid Optical/Digital processor is considered for the hardware implementation because their respective proven advantages seem to complement each other for this specific use. preliminary experimental results, in support of the theoretical work, are reported.
