Motion detection using fuzzy logic comparator

On-line digitalization of video camera images and the processing of the entire frame within 1/25 th of the second enables complex calculation of the security functions to be performed in real time. It is therefore possible to detect the presence of new moving objects with the use of a fuzzy pattern comparator. The authors outline the time filter required to perform motion detection. The processing of the above functions is divided into two parts: those processed by the host processor and the others performed by the fuzzy pattern comparator. As there are some possibilities for parallel processing the authors show the organization of the programming system with emphasis on the sharing of tasks between the two resources. The paper shows that real-time monitoring functions are possible with general purpose and additional multimedia hardware. Performances of the system are shown through examples.
