Deblurring Images Using the Blind Deconvolution Algorithm

WebbThe first restoration, described by J1 and P1, uses an undersized array, UNDERPSF, for an initial guess of the PSF. The size of the UNDERPSF array is 4 pixels shorter in each dimension than the true PSF.

Webb[J,PSF] = DEconVBLInD (I,InITPSF) deconvolves image I using maximum likelihood algorithm, returning both deblurred image J and a restored point-spread function PSF. The resulting PSF is a positive array of the same size as the InITPSF, normalized so its sum adds to 1. The PSF WebbYou must make an initial guess at the PSF. To determine the size of the PSF, examine the blurred image and measure the width of a blur (in pixels) around an obviously sharp object. Because the size of the PSF is more important than the values it contains, you can typically specify an array of 1's as the initial PSF.
