ABSTRACT:
Artifacts in an image introduced by sub-Nyquist aliasing are reduced below a visually perceptible level by a method comprising the steps of: providing an input image having sub-Nyquist aliasing artifacts; using a visual perception algorithm to identify the location and characteristics of the sub-Nyquist aliasing artifacts, thereby generating artifact coordinates and parameters; and processing the sub-Nyquist aliasing artifacts by reference to the artifact coordinates and parameters to reduce their visibility, thereby providing an artifact corrected image.
