METHOD FOR RECOVERING SIGNAL FOR REDUCTION OF GIBBS PHENOMENON OR RINGING ARTIFACT AND APPARATUS THEREOF

摘要

Disclosed are a method and an apparatus for recovering a signal for removing Gibbs phenomenon and a resonance artifact. The apparatus for recovering a signal prepared by the present invention recovers the resolution of a measured signal using an estimated signal and a measured signal in an image system for an original input signal. In addition, the apparatus recovers the final image signal by repeatedly performing a process of recovering the resolution in order to minimize the total variation of the recovered signal. At this time, the total variation of the recovered signal is the sum of variation on the surroundings based on the signal.
