Abstract
Deblurring a blurry image () includes the steps of (i) computing a spatial mask (); (ii) computing a modified blurry image () using the blurry image () and the spatial mask (); and (iii) computing a latent sharp image () using the modified blurry image () and a point spread function (). Additionally, the image () can be analyzed to identify areas of the image () that are suitable for point spread function estimation. Moreover, a region point spread function () can be analyzed to classify the point spread function(s) as representing (i) motion blur, (ii) defocus blur, or (iii) mixed motion blur and defocus blur. A point spread function () can also be estimated.
