Noise filtering in solar speckle masking reconstructions

Abstract

A new method of obtaining a sensitive noise lter for solar speckle masking reconstructions is presented below. This lter separates the true image information from noise most reliably. Its e ciency is demonstrated by some representative examples considering observed and arti cial image data which were generated in a computer. The latter set of data also su ered realistic degradations by the influence of seeing and noise taken from suitable observations.
