“…Shunting inhibitory cellular neural networks (SICNNs), which introduced by Bouzerdoum and Pinter (1993), have been studied and developed extensively in the past few decades by many authors due to their extensive applications in psychophysics, speech, perception, robotics, adaptive pattern recognition, vision, image processing and many other fields. We refer the reader to Bouzerdoum and Pinter (1993), Chen and Cao (2002), Chen and Zhao (2008), Chérif (2012), Ding and Ye (2009), Fan and Shao (2010), Liu et al (2007Liu et al ( , 2006, Ou (2009), Shao et al (2009) and Wu (2011). Consider a two-dimensional grid of processing cells, let C ij denote the cell at the (i, j) position of the lattice, the r-neighborhood N r ði; jÞ of C ij is given as N r ði; jÞ ¼ fC kl : maxðj k À i j; j l À j jÞ r; 1 k m; 1 l ng:…”
