Abstract
Blur is an well-known model for image and singal degradation. Deblurri ng, an inverse of blur is an ill-posed problem and its approximation s olution based on regularization exists in a restricted domain of Polyn omials or functions. We have observed that (1) Blurring operator is cl osed in our domain of definition, and (2) area of deblurred output is approximately 2e square-root pi for the deblurring kernerls in terms o f Weber parabolic cylinder functions and the gaussian N(0, square-root 2) blur.
