Systems And Methods For Deblurring Data Corrupted By Shift Variant Blurring

A machine readable medium for storing a machine executable program for deblurring data corrupted by shift variant blurring comprising:

• machine readable code for providing a first version of data having shift variant blurring characterized by a first shift variant point spread function;
• machine readable code for selecting a target shift invariant point spread function;
• machine readable code for deriving a second shift variant point spread function wherein a combination of the first and second shift variant point spread functions generates the target shift invariant point spread function;
• machine readable code for applying the second shift variant point spread function to the first version of the data thereby generating a second version of the data having shift invariant blurring characterized by the target shift invariant point spread function;
• and
• machine readable code for applying a linear shift invariant filter to the second version of the data thereby generating a deblurred version of the data.

A method of deblurring data corrupted by shift variant blurring, the method comprising:

• providing a first version of data having shift variant blurring;
• blurring the first version of the data further using a shift variant blurring kernel thereby generating a second version of data having shift invariant blurring;
• and
• applying a linear shift invariant filter to the second version of the data thereby generating a deblurred version of the data.
