According to the characteristics of the nonlinear response function of the CCD camera
a neural network image denoising scheme was proposed
which was based on the adaptive window size and parameter of the filter.Due to the neural network(NN)'s excellent nonlinearity
an improved method for neural network(NN) was applied.The new NN classified the CCD PTC(photon transfer curve) in nonlinearity and adjusted optimum filter window size and parameter to remove the noise adaptively.Experiment and theory analysis prove that the filter can remove the noise apparently with reserving the image edge details and improving the SNR
the filter also enhances the efficiency and precision of the image processing by improving the deficiency of BP method.
