摘要：A method for creating a mask for separating halftone regions in a binary imagefrom other regions comprises: constructing a seed image that includes pixels only in
halftone regions and at least one pixel in every halftone region (67); constructing aclipping mask that covers in a connected manner all ON pixels in halftone regions (70);and filling the seed while clipping to the mask (72). Thresholded reductions andmorphological operations are preferred.
