摘要： The present disclosure relates to providing a user interface for the effective generation of differential gloss images. The user is instructed to indicate the base primary image data, and the desired gloss image data. This data may be displayed for verification and position adjustment by superimposition of the gloss image data upon the base image data. In an alternative, the placement information may be inferred from the position of originals upon the scanner or copier platen and the result may or may not be displayed. By selectively applying halftones with different anisotropic structure orientation characteristics to the base primary image data as directed by the desired gloss image data, a differential gloss image file or hardcopy may be provided.

摘要： A method for adjusting the lightness/darkness of a binary halftone image includes receiving digital image data defining a binary halftone image in terms of a plurality of light pixels having a first value and a plurality of dark pixels having a second value. If the binary halftone image is to be lightened, the first value for each light pixel is moved in a direction away from the second value by a select amount so that it lies outside of the valid dynamic range. If the binary halftone image is to be darkened, the second value for each dark pixel is moved in a direction away from the first value by a select amount so that it lies outside of the valid dynamic range. Error diffusion is then performed on the binary halftone image to move all pixel values into the dynamic range. In the case of lightening the image, the error diffusion operation converts some dark pixels to light pixels. In the case of darkening the image, the error diffusion operation converts some light pixels to dark pixels. Propagated error in the error diffusion operation is limited by a preset amount.

摘要： A red-eye detection method includes receiving digital image data that defines an image. The digital image data are processed to identify all regions of the image that include a specular reflection. Image regions deemed to include a specular reflection are processed further, according to conventional techniques, to determine the presence or absence of red-eye. Specular reflections are identified according to luminace-chrominance characteristics, geometric (e.g., size/shape) characteristics, and/or luminance gradient characteristics.

摘要： A method for calibrating a printer includes printing a first set of color samples with the printer, reflecting at least a portion of the printer gamut. Each printed color sample in the set of samples is measured calorimetrically, to determine the printer's response thereto. The colorimetric response is compared with a predictive model of printer behavior for that portion of the printer gamut. In a portion of the printer gamut wherein the calorimetric response differs from predicted printer behavior, the printer generates a new set of color samples, for printing. The new set of color samples is secondarily measured to determine the printer's colorimetric response thereto; and using the initial measurements and the secondary measurements, a color calibration table is generated for use by the printer in converting device independent colors to device dependent colors.

摘要： An improved technique for processing a color or gray scale pixel map representing a document is disclosed. The pixel map is decomposed into a three-plane representation, a reduced-resolution “upper” plane, a reduced-resolution “lower” plane, and a high-resolution binary selector plane. The “upper” and “lower” planes contain the color or gray scale for the page as well as the continuous tone pictures that are contained on the page. The selector plane stores information for selecting from either the foreground plane or background plane during decompression. Information contained in the selector plane is first used to pre-process the upper and lower planes to reduce the amount of data on each of the other two planes that will be subjected to further processing. Each of the pre-processed planes is compressed using a compression technique optimal for the type of data that resides upon it.

摘要： A method and apparatus are provided for improving the quality of a printed image by first automatically determining the gamma (&ggr;) of an image, and then adjusting the &ggr; of the printer, if necessary, to correspond to that of the image. Thus, if an image has a &ggr; of 2, the &ggr; of the printer will be adjusted from approximately 1 (its normal &ggr;), to approximately 2 (i.e., corresponding to that of the image). To detect the &ggr; difference problem, the invention detects a shift in saturated colors towards higher digital counts. Then, through mapping of the color space from three dimensions to two dimensions and cross-plotting values of saturation and luminance, a cumulative histogram plot of luminance is developed. The histogram displays the 256 luminance bands, arranged in one of eight bands, and normalized from zero to one. A threshold value is established for the cumulative histogram plot and the value of the cumulative histogram is compared to the threshold. If the threshold is exceeded in most of the bands, the &ggr; for the image matches that of the printer. However, if the threshold is not exceeded, a false &ggr; image may be indicated, for example. In this case, the &ggr; of the printer may be automatically adjusted (e.g., increased from approximately 1 to approximately 2). Thus, the printed image will then be of the same quality as the original image.
摘要翻译：提供了一种方法和装置，用于通过首先自动确定图像的伽马（gamma）来改善打印图像的质量，然后如果需要，则调整打印机的伽玛以对应于图像的伽马（gamma）。因此，如果图像的伽马值为2，打印机的伽马将从大约1（其正常伽马）调整到大约2（即，对应于图像的伽玛）。为了检测伽马差异问题，本发明检测饱和颜色向较高数字计数的偏移。然后，通过将颜色空间从三维映射到二维和交叉绘制饱和度和亮度值，开发了亮度的累积直方图。直方图显示布置在八个频带之一中的256个亮度带，并从零归一化为一。对累积直方图绘制阈值，并将累积直方图的值与阈值进行比较。如果在大多数频带中超过了阈值，则图像的伽玛与打印机的伽玛匹配。然而，如果不超过阈值，则可以指示假伽马图像。在这种情况下，可以自动调整打印机的伽玛（例如，从大约1增加到大约2）。因此，打印的图像将具有与原始图像相同的质量。

摘要： The present invention is a method and apparatus for automatic image segmentation using template matching filters. The invention generally segments differing binary textures or structures within an input image by passing one or more structures while removing other structures. More particularly, the method and apparatus segment a stored binary image using a template matching filter that is designed to pass therethrough, for example, text regions while removing halftone regions.
