摘要： A method for generating a clustered halftone representation of a continuous-tone image for printing includes applying a search technique. In the search technique, evaluation of a similarity between an initial halftone and the continuous-tone image includes application of an initialization filter to an initial error image that represents a difference between the initial halftone and the continuous-tone image. Evaluation of a similarity between each updated halftone, formed by modifying a previously-evaluated halftone, and the continuous-tone image includes application of an update filter that is different from the initialization filter to an updated error image that represents a difference between the updated halftone and the continuous-tone image. Relating computer program product and data processing system are also disclosed.

摘要： A method for predicting an appearance of a rendering by a printer of a digital halftone representation of a continuous-tone image includes calculating a predicted absorptance value of a dot of a rendered halftone of the digital halftone representation. The dot corresponds to a pixel of the digital halftone representation. The predicted absorptance value is based on a configuration of pixel values of pixels in an immediate neighborhood of the pixel, and on a weighted contribution of a pixel value of each pixel in an outer neighborhood of the pixel. The method may be incorporated into a halftoning technique. Relating computer program product and data processing system are also disclosed.
摘要翻译：用于预测连续色调图像的数字半色调表示的打印机呈现外观的方法包括计算数字半色调表示的再现半色调的点的预测吸收值。点对应于数字半色调表示的像素。预测的吸收率值基于像素的紧邻区域中的像素的像素值的配置以及像素的外部邻域中的每个像素的像素值的加权贡献。该方法可以并入半色调技术中。还公开了关于计算机程序产品和数据处理系统。
