摘要
A method for creating a mask for separating halftone regions in a binary image from 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 a clipping 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 and morphological operations are preferred.
