摘要： A method and system electronically fuzzy classify a pixel belonging to a set of digital image data with respect to a membership of the pixel in a plurality of image classes. This process determines a fuzzy classification of the pixel and generates an effect tag for the pixel based on the fuzzy classification determination. Each class is defined by a set of heuristic rules such that the image classes are non-mutually exclusive. The heuristic rules are a set of conditions that define the membership value of the pixel within a certain class, thereby allowing a pixel to have a membership value in every possible image class.
摘要翻译：电子模糊方法和系统相对于多个图像类别中的像素的隶属度来归类属于一组数字图像数据的像素。该过程确定像素的模糊分类，并且基于模糊分类确定为像素生成效应标签。每个类由一组启发式规则定义，使得图像类是非互斥的。启发式规则是一组条件，用于定义某个类中像素的隶属度值，从而允许像素在每个可能的图像类中具有隶属值。

摘要： A system and method classify a pixel of image data as one of a plurality of image types. A first image characteristic value for the pixel, a second image characteristic value for the pixel, a third image characteristic value for the pixel, and a fourth image characteristic for the pixel is determined. Some of these determinations may be resolution dependent. The values from these determination are utilized in assigning an image type classification to the pixel. Moreover, if at least one of the image characteristic values is greater than a predetermined threshold value the pixel is classified as a halftone peak value. The system includes a plurality of microclassifiers for determining a distinct image characteristic value of the pixel; a plurality of macroreduction circuits connected to the plurality of microclassifiers for performing further higher level operations upon the distinct image characteristic values of the pixel to produce reduced values; and a classification circuit to classify the pixel as an image type based on the reduced values from the macroreduction circuits. The system also includes a circuit to detect flat peaks without detecting multiple peaks and a rectangular blur filtering system.

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 printing system for rendering marks on a recording medium receives a multi-level grey scale pixel value representing a pixel having a first resolution. A screening circuit generates a screened multi-level grey scale pixel value equal to (G.sub.L -V.sub.i)+(S.sub.i -Th)*Dmp.sub.Vi *Mod.sub.Eff wherein G.sub.L is the maximum grey level value of the pixel, V.sub.i is equal to the multi-level grey scale pixel value of the first resolution, S.sub.i is equal to a screen value corresponding to a position of the pixel, Th is the threshold value, Dmp.sub.Vi is a video dependent dampening factor, and Mod.sub.Eff is a modulation multiplication factor. An interpolator converts the screened multi-level grey scale pixel value to a second resolution, the second resolution being higher than the first resolution, and a binarization circuit binarizes the converted multi-level grey scale pixel value so as to output a binary signal and an error value, the error value having a resolution equal to the first resolution. The error value is diffused to multi-level grey scale pixel values corresponding to pixels adjacent to the pixel having the first resolution, and the binary signal is converted into a mark on the recording medium.

摘要： A method and system implements a redistributive characteristic into an error diffusion process. A grey level value representing a pixel is received. A threshold circuit thresholds the received grey level value and generates an error value as a result of the threshold. A portion of the error value is diffused to adjacent pixels on a next scanline. All the error for a single pixel on the next scanline is accumulated. Since this accumulated error has a greater number of bits than can be stored in a buffer, a portion of the accumulated error is truncated and redistributed to a down stream pixel for inclusion in the downstream pixel's error accumulation process. The grey level value has a first resolution which corresponds to an original input resolution. In a high addressabilty environment, the received grey level value is interpolated to subpixel grey level values before thresholding.
摘要翻译：一种方法和系统在误差扩散过程中实现再分配特性。接收表示像素的灰度值。阈值电路对接收的灰度级值进行阈值，并作为阈值的结果生成错误值。错误值的一部分扩散到下一个扫描线上的相邻像素。累积下一个扫描线上单个像素的所有错误。由于该累加误差具有比可以存储在缓冲器中更多的位数，所以累积误差的一部分被截断并重新分配给下行像素以包括在下游像素的误差累加处理中。灰度值具有对应于原始输入分辨率的第一分辨率。在高可寻址环境中，接收到的灰度值被内插到阈值处理之前的子像素灰度值。

摘要： Method and apparatus for processing image pixels to determine the presence of high frequency halftone images. Prior to auto correlation, each pixel in the image is examined to determine whether it is a local area maximum or minimum. A binary image function composed of the image local area maximum or minimums is made available for auto correlation. The presence of peaks at shifts indicative of predetermined halftone image frequencies is detected, and an output signal indicative of the presence or absence of peaks at the predetermined halftone image frequencies is provided. The arrangement is combined with a run length encoder to reduce false microdetection results.
