Abstract

The disclosed system has particular applications to image archives and reediting. Given an image of an article having graphic objects including texts and pictures, the disclosed system first distinguishes graphic objects from the background by segmenting the image so as to produce an object image comprising a foreground, wherein the foreground corresponds to the graphic objects in the image. With respect to the foreground, the disclosed system 'repaints' those spaces previously occupied by the graphic objects, referred to as object spaces, with the background color in the image as such the background continuity is preserved when the graphic objects are rendered and subsequently superimposed onto the repainted background. To account for various backgrounds, the disclosed system uses a point-wise patching approach followed by a one-dimensional patching approach if the object spaces contain two different colors. In addition, a two-dimensional patching approach is implemented to account for printing effects such as half-toning and mosaic patterns.
