Webb[J,PSF] = deconvblind(I,INITPSF,NUMIT,DAMPAR,WEIGHT)specifies which pixels in the input image, I, are considered in the restoration. By default, WEIGHTis a unit array, the same size as the input image. You can assign a value between 0.0 and 1.0 to elements in the WEIGHTarray. 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 following figure shows a restoration where the initial guess at the PSF is the same size as the PSF that caused the blur. In a real application, you might need to rerun deconvblind, experimenting with PSFs ...
