摘要： A grayscale two-dimensional barcode may be converted to a two-dimensional color barcode. The color barcode includes a set of sub-regions, and the cells in each sub-region exhibits a color pattern that corresponds to pattern of binary, grayscale cells. The two-dimensional color barcode may be decoded by comparing the pattern for each sub-region to a known grayscale pattern. The two-dimensional color barcode may be used for error correction by first decoding the barcode in grayscale form based on the luminance without reference to color, then decoding the barcode based on its color and comparing the results.

摘要： Methods are provided for creating a fluorescent watermark within an image on a substrate, such as paper. The method involves creating a halftone image using two different halftone strategies. The halftone method is combined with a binary watermark mask to form two color patterns (e.g., one in a background region of the image and one in a watermark region of the image) and two successive-filling halftone algorithms, such that the ink droplets deposited by one color pattern cover more of the substrate than the ink droplets deposited by the other color pattern, with the two color patterns having approximately the same reflectance under normal light. However, under UV illumination, a visible difference (e.g., the watermark) is seen in the two patterns.

摘要： Systems and methods are described that facilitate generating a background image with a UV-fluorescent watermark for printing on a document. A binary watermark mask is generated to separate the background image into the UV-active and the UV-dull regions. Based on the assigned binary value of the watermark mask, each pixel is assigned a UV-active or UV-dull color using an adaptive halftoning technique, in order to generate a binary UV-active image and a binary UV-dull image. A binary watermarked background image is generated by combining the binary UV-active and UV-dull images, and is printed on a document. The UV-active and UV-dull colors have different UV intensities under UV light, but are indistinguishable under normal lighting conditions. In this manner, the background image is visible when exposed to visible light, and the UV-fluorescent watermark is visible when exposed to UV light.
摘要翻译： 描述了利用用于在文档上打印的UV-荧光水印产生背景图像的系统和方法。 生成二进制水印蒙版以将背景图像分离成UV活性和UV-暗区域。 基于水印蒙版的分配的二进制值，使用自适应半色调技术为每个像素分配UV活性或UV-暗颜色，以便生成二值UV活性图像和二进制UV-暗图像。 二进制水印的背景图像是通过组合二进制UV-活动和UV-暗色图像来生成的，并被打印在文档上。 紫外线和紫外线的暗色在紫外光下具有不同的UV强度，但在正常的照明条件下是不可区分的。 以这种方式，当暴露于可见光时，背景图像是可见的，并且当暴露于UV光时，UV-荧光水印是可见的。

摘要： A software application corrects for luminance and/or color in a captured image on a device having two cameras. The first camera receives a reference image, and the second camera receives a target image. The device compares the reference image and a reference file retrieved from memory to identify one or more luminance or color differences, and it automatically actuates an optical adjustment element of the second imaging device in response to the differences. The second imaging device captures a target image, and the target image is stored in a computer-readable memory.
