Abstract : In this paper , a multiwavelet based method is proposed to estimate the blur in an image using information contained in the image itself . We look at the sharpness of the sharpest edges in the blurred image , which contain information about the blurring . Specifically , a smoothness measure , the Lipschitz exponent , is computed for these sharpest edges . A relation between the variance of a gaussian point spread function and the magnitude of the Lipschitz exponent is shown , which is only dependent on the blur in the image and not on the image contents . This allows us to estimate the variance of the blur directly from the image itself .
