It is very important that extracting the center of interference - stripes in the interference measurement. A new method to extract the center of interference - stripes using cellular neural networks （CNN） is described. As a large - scale nonlinear analog circuit, the CNN is suitable for real- time signal and image processing. The CNN can be used for high- speed parallel computation and is easy to be translated into a VLSI implementation. A two - dimensional CNN that performs an algorithm to extracting the center of interference - stripes is proposed. Some practical results are presented and briefly discussed, which demonstrates the successful operation of the proposed algorithm.
