Abstract
A method of removing an artefact from an image captured with a motion invariant camera is disclosed. The captured image is de-blurred using a spatially invariant blur kernel. An edge filter with a fixed offset is applied to the de-blurred image to identify the location of at least one artefact. A parameter is estimated based on a region either side of the identified location. The at least one artefact is removed from the de-blurred image using the parameter.
