Abstract

An application of a blind-deconvolution technique to defocused images is described. The power spectrum of the out-of-focus blurring function is estimated by averaging the spectrums of subimages of the blurred image. The phase response is then identified from both the power spectrum and the power cepstrum of the blurring function. The identified blurring function is used with both Wiener and homomorphic filters to perform restoration.
