Abstract
The automated TV-set aster tuning system capable to control the vertical and horizontal size and position,pin cusion,trapezoid,parallelogramm and tilt has been developed.To solve the problem of non-linearity and non-symmetry approximation the neural network with activation function based on the Volterra series was used.The new algorithm invariant to oscillation of brightness based on neocognitron neural network was applied for processing the grayscale images of integ al circuits.
