Image Deblurring

Deblurring is a process that removes distortion from a blurry image using knowledge of the point spread function.

Creating Your Own Deblurring Functions

To create your own deblurring functions, convert the distortion operator between the spatial and the frequency domains using the otf2psf and psf2otf functions.

Avoiding Ringing in Deblurred Images

To avoid "ringing" around edges in deblurred images, use the edgetaper function.
