Theoretical Analysis and Realization of Restoration of Wiener Filtering

Satisfactory effect of restoration of motion-blurred image can be gained through simulation experiment based on the model of fuzzy mathematics.Point-spread function(PSF) plays a key role in image restoration.As a result,prior knowledge and posteriori estimation of PSF is usually used to restore image.Experiments show that the impact of signal noise ratio,autocorrelation function(ACF) of noise and autocorrelation function of the original image must be taken into consideration when noise is accidentally mixed in the process of restoration of motion-blurred image.
