“…In systems employing tracking, the area of interest (AOI) is recognised using a highresolution camera and is handed over to the low-resolution receiver for further tracking (Kishore 1989). Acquisition and recognition of an object depend on field of view (FOV), object size, sensor resolution etc.…”

“…The suitable preprocessing algorithm has been described in a report by Boland et al (1977). The performance of the preprocessing algorithm (PA) has been studied using COMTAL±Micro Vax Image processing system and is found to be satisfactory (Kishore 1989). The automatic target handing-over system has been designed and developed using iAPX 86 family of microprocessors (Kishore 1994).…”

In systems employing tracking, the area of interest is recognized using a high resolution camera and is handed over to the low resolution receiver. The images seen by the low resolution receiver and by the operator through the high resolution camera are different in spatial resolution. In order to establish the correlation between these two images, the high-resolution camera image needs to be preprocessed and made similar to the low-resolution receiver image. This paper discusses the implementation of a suitable preprocessing technique, emphasis being given to develop a system both in hardware and software to reduce processing time. By applying different softwareahardware techniques, the execution time has been brought down from a few seconds to a few milliseconds for a typical set of conditions. The hardware is designed around i486 processors and software is developed in PL/M. The system is tested to match the images obtained by two different sensors of the same scene. The hardware and software have been evaluated with different sets of images.
