摘要： A method is presented for deriving gamma for a display monitor that does not involve color matching tasks. The method includes displaying a test pattern to a user on the display monitor. The test pattern includes at least one of a pattern of alternating light and dark regions displayed to the user at different gamma correction levels, or a grayscale character string displayed to the user at different digital gray levels against a background of two known luminance levels. Input is received from the user as to at least one of a gamma correction level that results in the pattern of alternating light and dark regions having light and dark regions of perceived equal size, or a digital gray level for the grayscale character string that results in maximum legibility of the text string against the two known background luminance levels. Gamma is derived for the display monitor based upon the user input.

摘要： As set forth herein, a computer-implemented method facilitates replacing text on cylindrical or curved surfaces in images. For instance, the user is first asked to perform a multi-click selection of a polygon to bound the text. A triangulation scheme is carried out to identify the pixels. Segmentation and erasing algorithms are then applied. The ellipses are estimated accurately through constrained least squares fitting. A 3D framework for rendering the text, including the central projection pinhole camera model and specification of the cylindrical object, is generated. These parameters are jointly estimated from the fitted ellipses as well as the two vertical edges of the cylinder. The personalized text is wrapped around the cylinder and subsequently rendered.
摘要翻译：如本文所述，计算机实现的方法有助于在图像中的圆柱形或弯曲表面上替换文本。例如，首先要求用户执行多边形的多点选择以绑定文本。进行三角测量方案来识别像素。然后应用分割和擦除算法。通过约束最小二乘拟合精确估计椭圆。生成用于呈现文本的3D框架，包括中心投影针孔相机模型和圆柱形对象的规格。这些参数是从安装的椭圆以及气缸的两个垂直边缘共同估计的。个性化文字包裹在圆柱体上并随后呈现。

摘要： A method and system convert an original digital image being represented by a first color space to a digital image being represented by a second color space by transforming the original image data represented by a first color space to second image data being represented by a second color space, the transformation causing the colors of the transformed image data to be substantially encodable in the second color space. The second image data represented by the second color space is transformed to third image data represented by the first color space, the transformation causing the colors of the transformed image data to be substantially encodable in the first color space. Distortions in the third image data represented by the first color space are corrected to form corrected image data represented by the first color space, and the corrected image data represented by the first color space is transformed to fourth image data represented by the second color space.

摘要： A watermark can be embedded in an image that has the property of being relatively indecipherable under normal light by including a distraction pattern, and yet remains decipherable under infrared illumination when viewed by a suitable infrared sensitive instrument. This infrared mark comprises, a substrate reflective to infrared radiation, a foreground colorant mixture printed as an image upon the substrate, a background colorant mixture and a distraction colorant mixture. A resultant collocated image rendered substrate suitably exposed to an infrared illumination, will yield a discernable image evident as a infrared mark to a suitable infrared sensitive device, but remain undecipherable under normal ambient light.

摘要： Identifying the substrate type of a target substrate before patterning by a marking engine produces an opportunity to adjust the marking engine. The adjustments can enable the marking engine to produce higher quality work. The target substrate's substrate type can be automatically identified by obtaining its characteristics and submitting them to a classifier. A spectrophotometer can measure a substrates reflectance spectrum, which is a good characteristic for use in classifying. Classifiers can be based on known distance or correlation measures.

摘要： The teachings as provided herein relate to a watermark embedded in an image, and methodology for same, that has the property of being relatively indecipherable under normal light, and yet decipherable under UV light. This fluorescent mark comprises a substrate containing optical brightening agents, and a first dot design printed as an image upon the substrate. The first dot design has as a characteristic, the property of strongly suppressing substrate fluorescence. A second dot design having a property of providing a differing level of substrate fluorescence suppression from that of the first dot design such that when rendered in close spatial proximity with the first dot design image print, the resultant image rendered substrate suitably exposed to an ultra-violet light source, will yield a discernable image evident as a fluorescent mark.

摘要： An image characterized by an original image gamut is received in an imaging device characterized by a device gamut. The original image gamut is enhanced to a first set of modified color values that occupy a greater fraction of the device gamut than the original image gamut. The modified color values of each pixel are mapped to new color values within the device gamut.
