Abstract: A watermarked image generator includes a watermark data source that inputs watermark data to a watermark embedding device. The watermark embedding device halftones the input image to generate the output image made of 2×2 binary patterns, the 2×2 binary patterns forming the watermarks embedded in the output image. The watermark embedding device includes a tri-level error diffusion generator that performs tri-level error diffusion on the input image by halftoning the input image into black, white and 50% gray. A plurality of halftoning circuits successively replace each pixel of the halftoned input image with one of a plurality of the 2×2 binary patterns. The one of the plurality of 2×2 binary patterns corresponds to at least one respective bit of the watermark data when a pixel of the halftoned image data is 50% gray. The watermark data can be segmentation map data of the input image.

Abstract: A method and system which converts an electronic binary image to another electronic binary image by compensating for the differences between printer responses so that a target printer can print the image to emulate how the image would appear if printed by an originally-intended printer or another printer. A print-ready binary image is inputted into a print and scan simulation circuit which electronically simulates the printing and scanning of the image data. The print and scan simulation circuit converts the binary image data to gray scale image data. The gray scale image data is then processed by a tone response correction circuit. The tone response correction circuit alters the gray scale image data based on the difference between the tone reproduction curves of two printers, such as an originally-intended printer and a target printer. This changes the value of each pixel so that it ultimately yields the same density on the target printer when it is converted to binary form and printed as it would if the original binary image were printed on the originally-intended printer. This altered gray scale image data is then sent to a binarization circuit which converts the gray scale image data to a binary image. This binary image may then be sent to a printer, such as the target printer, so that the quality of the printed binary image simulates how it would have been printed on the originally intended printer.

Abstract: A digital image processing system for automatically segmenting a set of input image signals into a combination of predetermined classes of imagery, the set of input image signals forming part of a video image generated by an image input terminal. The system includes a classification circuit that receives the set of input image signals and classifies them as a ratio of the predetermined classes of imagery. A plurality of image processing circuits also receives the set of input image signals, each of which is adapted to process a unique class of imagery selected from the predetermined classes of imagery to generate a set of output image signals for that predetermined class of imagery. Finally, a mixing circuit combines each of the sets of output image signals determined by the plurality of image processing circuits in accordance with the ratio determined by the classification circuit to form a single set of output image signals, the mixing circuit minimizing the generation of artifacts formed in the single set of output image signals by providing a gradual transition between each of the predetermined class of imagery.

Abstract: A method to detect frequency and angle of a binary halftone pattern. The method employs an exclusive-or operation which is applied locally to a region of a binary bit map and its spatially shifted version. The resulting bits from the exclusive-or operation are summed over the region. The exclusive-or operation is repeated for a range of shift values. In a halftone region, the shift at which the minimum sum occurs reflects the angle and the frequency of the halftone.

Abstract: Systems and methods are presented for processing and rendering image data during a single pass through the image data. A method includes loading scanlines of image data into a rolling band buffer, performing a windowing technique on the image data, and determining if a class change was experienced by any window having a portion in an output scanline of the buffer. The method further includes processing image data in the output scanline for a window portion that experienced a class change, using a blended rendering algorithm. If no class change is detected, the method includes processing image data in the output scanline for the window portion using a class-based rendering algorithm. The method optionally includes rendering processed image data for the output scanline to a rendering device. According to other features, an apparatus includes a rolling band buffer, a windowing processor, class-based rendering algorithms, and a blended rendering algorithm.

Abstract: A method for neutral pixel detection using color space feature vectors wherein one color space coordinate represents lightness is provided. The method includes the following steps: a) receiving an input image represented in a first color space; b) converting the input image to a second color space wherein one coordinate represents lightness; c) selecting a pixel in the second color space representation to be classified; d) computing second color space feature vectors associated with the selected pixel; and e) classifying the selected pixel between neutral and color classes based on the values computed for the second color space feature vectors. Typically, the input image is processed using a smoothing filter to create a smoothed input image prior to the conversion to the second color space. The method can be adapted to page processing or strip processing schemes with respect to the input image.
