摘要： Methods and apparatus for segmenting image data into windows and rendering a best-estimate outline delineating document windows may include adjusting a background white threshold differently than adjusting a white threshold normally used to classify pixels as white for video processing purposes. Such an independently arrived at threshold may be more suitable for the different task of differentiating between document background and document content.
摘要翻译：将图像数据分割成窗口并渲染描绘文档窗口的最佳估计轮廓的方法和装置可以包括调整背景白色阈值，而不是调整通常用于将像素分类为白色的白色阈值用于视频处理目的。这样独立地达到阈值可能更适合区分文档背景和文档内容的不同任务。

摘要： Methods and apparatus for segmenting image data into one or more windows may collect statistics on white regions, otherwise called enclosed white windows. Such enclosed white windows may be merged with one of a surrounding nonwhite window and a background based upon the enclosed white window's size, edge characteristics, cumulative statistics and/or at least one control parameter. Such merging may be accomplished at a time subsequent to enclosing the white region or dynamically while the window is being assembled scanline-by-scanline.

摘要： A method and system for processing image data in an image processing device for a plurality of pixel positions within a plurality of scanlines. The method and system includes storing a starting stamp value and a plurality of delta stamp values for the scanline. The stored values being used to generate a pixel stamp value for an input pixel in the scanline, by adding a starting value or previous pixel stamp value and the stored delta stamp value for the input pixel. Further includes receiving an input pixel intensity value for the input pixel and determining an output pixel intensity value. Subsequently, if the output pixel intensity value for the input pixel is equal to a value for a dot or hole the delta stamp values for at least one pixel having a location previous or subsequent to the input pixel can be updated.

摘要： A method of printing comprising setting a pixel black value of K for an ink limit and identifying each of black dots of a first subset of black dots having pixel black value K greater than the ink limit, and pixel color value of cyan, magenta, and yellow equal to zero. The method further comprises rendering only K for a pixel value for the first subset of black dots and replacing each of black dots of a second subset of black dots of a halftoned bit map for a predetermined area with a process black dot. The method still further comprises adding a non-black dot to each of black dots of a third subset of black dots of the bit-mapped data, wherein the halftoned bit map is generated by halftoning continuous tone data; wherein the black dots of the third subset comprises a percentage of all the black dots that tends to generally increase as a ratio of black coverage to total coverage in the predetermined area increases; wherein the first, second, and third subset comprises black dots that are mutually exclusive; and, printing the bit map.

摘要： A system and method for performing threshold stamping are disclosed. First and second threshold values corresponding to first and second pixels may be retrieved from a threshold memory. A plurality of upscaled threshold values may optionally be computed based on the first threshold value and the second threshold value. An (upscaled) threshold value may be updated at each of one or more first register blocks. A binary pixel value may be computed based at least in part on the first updated threshold value. The first updated threshold value may be updated at each of one or more second register blocks. A downscaled threshold value may optionally be computed based on a plurality of second updated threshold values. The downscaled threshold value or second updated threshold value may be damped in a damping circuit, and the damped threshold value may be stored in the threshold memory.

摘要： A method and system for performing error diffusion is disclosed. An error value for a pixel may be received and used to determine one or more error diffusion values. The error diffusion values may be determined by performing bit shifting of the error value. Truncation of the error diffusion values may result in a difference between the error value and a sum of the error diffusion values. This difference may be compensated for by adding error compensation values to the error diffusion values to yield compensated error diffusion values. The compensated error diffusion values may then be diffused to appropriate destination pixels.
摘要翻译：公开了一种用于执行误差扩散的方法和系统。可以接收像素的误差值并用于确定一个或多个误差扩散值。可以通过执行误差值的位移位来确定误差扩散值。误差扩散值的截断可能导致误差值与误差扩散值之和的差异。可以通过将误差补偿值添加到误差扩散值来补偿该差异，以产生补偿的误差扩散值。然后可以将经补偿的误差扩散值扩散到适当的目标像素。

摘要： Methods and systems for performing resolution expansion with high quality edge enhancement capability utilizing an edge detector and a color estimator. An edge tag with respect to an input image can be detected via an edge detector and an edge detection approach. A resolution expansion can be separately applied to the edge tag and a binary output generated by other processing functions. Multiple output lines corresponding to the input image from the color estimator with different threshold array values for an edge pixel can be generated by a halftoning module. A binary domain resolution expansion can be applied for a non-edge pixel. A final output for each pixel can be selected from a resolution expanded result and/or from the result of the halftoning for the edge based on the edge tag with respect to that pixel.
