Restoration of an image degraded by vibrations using only a single frame

A recently developed method for the restoration of motion-blurred images is investigated and implemented for the special complicated case of image blu r due to sinusoidal vibrations. Sinusoidal vibrations are analyzed in the c ontext of blur identification and image restoration. The extent of the blur and the optical transfer function (OTF) are identified from the blurred im age by a straightforward process without the use of iterative techniques. T he blurred image is restored using a simple Wiener filter with the identifi ed OTF. The main novel achievement is the use of only a single vibrated blu rred image as input information, on which the restoration process is based. The various cases of blur types that depend on the imaging conditions are considered. Examples of blur identification and image restoration are prese nted.
