ABSTRACT:
A method and a system for separating an image signal into a set of image planes are disclosed. The system comprises a way to perform resolution conversion from low resolution to high resolution binary images either for synthetic or scanned imagery by using template matching with pattern replacement. More specifically, the invention applies resolution conversion to the selector plane of mixed raster content images. For selector planes in which edges are encoded (vs. region classification), template matching/pattern replacement works well, and does not affect halftoned regions, as they are not encoded in this image.
