Abstract :
The mathematical model of a cellular neural network (CNN) working in discrete time is considered. The possibility of such devices for computation of the convolution of a two-dimensional digital signal with a given kernel is shown. The algorithm for the construction of a difference equation with constant coefficient, which has the solution of a demanded convolution is given. The hardware implementation of this equation gives the structure of CNN. The model of an exponential smoothing filter of a two-dimensional digital signal is considered.
