We derive the relationship between the Fourier transform magnitude and the phase of the original signal from the degraded one. The phase of the original signal can then be specified uniquely from the Fourier transform magnitudes of the relevant signals and the phase of the degraded signal and the system transfer function.

A modified SNR for image evaluation for still pictures is presented. This is made by considering a characteristic of a subjective visual response to the image. Two different kinds of impairments which are most typical are considered here. One is a blurring and the other is a random noise.
