Blur identification by residual spectral matching
1993
IEEE Transactions on Image Processing
The estimation of the point function (PSF) is often a necessary first step in the restoration of real images. In this work, a new blur identification method is presented. The PSF estimate is chosen from a collection of candidate PSF's which may be constructed using a parametric model or from experimental measurements. The PSF estimate is selected to provide the best match between the restoration residual power spectrum and its expected value, derived under the assumption that the candidate PSF
