19 December 1985 Image Restoration Via The Shift-And-Add Algorithm
Author Affiliations +
A new method for image restoration based on the shift-and-add algorithm is presented, the main advantages of which appear to be speed and simplicity. The shift-and-add pattern produced by an object is given by the object correlated by a non-linear replica of itself whose intensity distribution is strongly weighted toward the brighter pixels. A method of successive substitutions analogous to Fienup's algorithm can then be used to "decorrelate" the SAA pattern and recover the object. The method is applied to the case of the extended chromosphere of Betelgeuse.
