Abstract

A practical hardware design of a two-dimensional (2D) analog filter proposed by M.A. Sid-Ahmed (IEEE Circ. and Syst., vol.36, p.153-4, Jan. 1989) is developed. The structure is implemented using charge coupled device (CCD) analog shift registers and wideband operational amplifiers. The operation of the filter is demonstrated by processing TV video images in real time. The 2D analog approach is evaluated by comparison with a 2D distributed arithmetic digital filter. The analog approach offers realization at lower cost, less power consumption, higher resolution, and inherent true real-time capability independent of filter order
