Abstract: A method and an arrangement for realizing true 2-D analog filtering structures of either IIR or FIR type in hardware using only analog devices and line delays. The wide variety of 2-D signal processing techniques that are based on a 2-D transfer function of general order can be implemented. 2-D analog filters are realized in hardware that can directly operate on a raster scanned image without the need for expensive frame stores, A/D and D/A converters. The high-speed operation inherent in the analog nature of the processing makes possible real-time operation at the high data rates of analog raster scanned images, even at high pixel resolution as in HDTV. Many applications involving TV imaging in such areas as advanced television systems, industrial and biomedical video systems are possible.
