Successful restoration of blurred images depends primarily on the knowledge about the degradation parameter.Defocus blur model in the frequency domain is characterized by concentric rings and the blur radius of the point spread function (PSF) can be identified conveniently in the frequency field for people by manual means rather than for computer.This paper introduces a practical method for computer to estimate the defocus blur parameter in cepstrum area.Fou…查看全部>>
