BPEJTC-based segmentation of a moving target in natural background

A novel BPEJTC-based method of extracting a moving target's signature residing in a background input is proposed. The efficiency of this method depends to a great extent on the degree of a JTC performance. A BPEJTC is shown to have a improved peak-to-sidelobe ratio than that of a conventional JTC. An optoelectronic system implementing this method is realized. In this system, time-consuming computations, like FFT are conducted optically while arithmetic operations are executed digitally such that the proposed hybrid system can operate in real-time. Some experimental results obtained with real input images indicate that the proposed system can effectively work even in a nonstationary background.
