Blur-Kernel Estimation from Spectral Irregularities

  title={Blur-Kernel Estimation from Spectral Irregularities},
  author={Amit Goldstein and Raanan Fattal},
We describe a new method for recovering the blur kernel in motion-blurred images based on statistical irregularities their power spectrum exhibits. This is achieved by a power-law that refines the one traditionally used for describing natural images. The new model better accounts for biases arising from the presence of large and strong edges in the image. We use this model together with an accurate spectral whitening formula to estimate the power spectrum of the blur. The blur kernel is then… CONTINUE READING
