One embodiment of the present invention provides a system that identifies halftone regions within a digital image. During operation, the system receives a region from the digital image, wherein the digital image is a bi-level image, wherein each pixel has two possible color values. Next, the system computes a variation index for a region of the digital image, wherein the variation index indicates how frequently adjacent pixel values in the region differ. If the variation index for the region is greater than an upper threshold, the system determines that the region is a halftone region.
