“…As a nonlinear analog processor with local interconnect and dual-value output, the cellular neural network (CNN) proposed by Chua et al in 1988 is particularly suitable for the implementation of large-scale circuits [1,2]. The results of CNN research have been widely used in many fields such as biomedicine [3], automatic control [4], pattern recognition [5], signal processing [6], and secure communication [7]. In particular, CNNs are the most extensively used in image processing including noise reduction, edge detection, and character recognition [8−10].…”
