Cellular neural networks (CNN) are a parallel computing paradigm similar to neural networks, with the difference that communication is allowed between neighbouring units only.

in this system, 'A' template is feedback matrix, and 'B' template is control matrix.
also, 'I' is Bias value.

all image processing morphological algorithm are doable in CNN and enhanced CNN.
