Restoring Images Degraded by Spatially-Variant Blur
Restoration of images that have been blurred by the effects of a Gaussian blurring function is an ill-posed but well-studied problem. Any blur that is spatially invariant can be expressed as a convolution kernel in an ...
Fast Iterative Image Restoration with a Spatially-Varying PSF
We describe how to efficiently apply a spatially-variant blurring operator using linear interpolation of measured point spread functions. Numerical experiments illustrate that substantially better resolution can be obtained ...
