Blind Estimation of PSF for Out of Focus Video Data


A method has been proposed for blindly estimating the Point Spread Function (PSF) of video data. The PSF’s of the images in a sequence are assumed to be of compact support and hence admit FIR modeling. The zeros (roots) of the Optical Transfer Function (OTF) i.e. the Fourier transform of the PSF are first estimated by locating the singularities of the… (More)
