摘要: A practical hardware design of a two-dimensional analog filter proposed by M.A. Sid-Ahmed (see IEEE Trans. Circuits and System vol.36, no.1, p.153-84, 1989) is developed. The structure implemented using charge coupled device (CCD) shift registers wideband operational amplifiers. operation the demonstrated processing TV video images in real time. approach evaluated comparison with distributed arithmetic digital filter. offers realization at lower cost, less power consumption, higher resolution, inherent true real-time capability independent order. >
