Perceptual evaluation of the mean-square error choice of regularization parameter.
A formal perceptual study shows that the perceptually optimal choice of regularization parameter varies from the minimum mean-square error parameter as a function of the original image, the point-spread function, and the signal-to noise ratio (SNR). However, further studies show that this variation has only a slight effect on the perceived quality of the restoration.
