摘要： An image analysis and conversion method and system. Bitmapped ink images are converted to structured object representations of the bitmapped images, which may be read and edited by a structured text/graphics editor. The structured object representations correlate to perceptually salient areas of the bitmapped images. The structured object representations are editable by the structured text/graphics editor to allow a user to generate alternative interpretations of the bitmapped images.

摘要： A device for registering component image tiles in a scanning system for transcribing, into electronic form, markings on a two-dimensional surface such as a whiteboard. A registration light pattern is projected onto the surface to be imaged. The pattern projected can be chosen to best suite the specific properties of the camera and imaging environment. The pattern markings are processed using perspective transformations to determine the overlap properties of the image tiles and distortion of each tile image, and the resulting data is used to combine the tiles to produce an undistorted composite image of the whiteboard.

摘要： A print management system includes a policy that determines a protection level for a document to be printed. The document is printed using forgery detection and deterrence technologies, such as fragile and robust watermarks, glyphs, and digital signatures, that are appropriate to the level of protection determined by the policy. A plurality of printers are managed by a print management system. Each printer can provide a range of protection technologies. The policy determines the protection technologies for the document to be printed. The print management system routes the print job to a printer that can apply the appropriate protections and sets the appropriate parameters in the printer. Copy evidence that can establish that a document is a forgery and/or tracing information that identifies the custodian of the document and restrictions on copying of the document and use of the information in the document are included in the watermark that is printed on the document. A document can be verified as an original or established as a forgery by inspecting the copy evidence and/or tracing information in the watermark.

摘要： A system for automatically generating indexes for handwritten notes captured as digital ink in a computer is disclosed. Ink words are identified, and features of the ink words are computed. Pairwise distances or match scores, which measure the distance in the features between two ink words, are calculated. A clustering technique selects equivalence classes of ink words. Index terms, which are non-uniform through-out the notes, are selected from the equivalence classes of ink words. The system generates an index from the index terms, including displaying pages numbers where the index terms are located in the notes as well as hyper-linking the index terms. A technique to identify a threshold for use in clustering the ink words is also disclosed.

摘要： A bistable flap array display in which flaps selectively cover portions of a background substrate in response to fluid flow and a flap catchment mechanism, each flap rendering at least one pixel of the display. The catchment mechanism can be electrostatically based and the fluid can reduce the charge required to operate the catchment mechanism by creating a partial vacuum that lifts the flaps until the flow can impinge on the flap directly.

摘要： Message values included in a set of valid message values that constitute a coding scheme are each encoded in an image region, called an encoded signal block, composed of a spatially arranged pattern of colored sub-regions. The colored sub-regions have color values produced by modulating a reference color value by a color change quantity expressed as a color space direction in a multi-dimensional color space such that the average color of all of the sub-region colors is the reference color. There is a unique pattern of color-modulated sub-regions for each valid message value in the coding scheme. In one embodiment, the color space direction is computed to be simultaneously detectable by a digital image capture device such as a scanner and substantially imperceptible to a human viewer, so that the embedded data represented by the pattern of color modulations are visually imperceptible in the encoded signal block. When the reference color is determined to be the average color of an image region in an original color image, the encoded signal block may replace the image region in the original image, producing an encoded image version of the original image having little or no image degradation. In this case, the original image colors become carriers of the encoded data. Signal blocks may be arranged to encode data in only one dimension in an image, which allows for less complex decoding algorithms, or in a two dimensional array or grid-like structure, which allows for a high encoded data density rate.
摘要翻译：包含在构成编码方案的一组有效消息值中的消息值分别被编码在由彩色子区域的空间排列图案组成的称为编码信号块的图像区域中。有色子区域具有通过在多维颜色空间中以颜色空间方向表示的颜色变化量调制参考颜色值而产生的颜色值，使得所有子区域颜色的平均颜色为参考颜色。对于编码方案中的每个有效消息值，存在着色调制子区域的独特模式。在一个实施例中，颜色空间方向被计算为可由诸如扫描仪的数字图像捕获设备同时检测，并且对人类观察者基本上不可察觉，使得由编码的颜色调制图案表示的嵌入数据在视觉上不可察觉信号块。当参考颜色被确定为原始彩色图像中的图像区域的平均颜色时，编码信号块可以代替原始图像中的图像区域，产生具有很少或没有图像劣化的原始图像的编码图像版本。在这种情况下，原始图像颜色成为编码数据的载体。信号块可以被布置成仅在图像中的一个维度上对数据进行编码，这允许较不复杂的解码算法，或允许高编码数据密度率的二维阵列或网格状结构。

摘要： A method and apparatus for processing a document image, using a programmed general or special purpose computer, includes forming the image into image units, and at least one image unit classifier of at least one of the image units is determined, without decoding the content of the at least one of the image units. The classifier of the at least one of the image units is then compared with a classifier of another image unit. The classifier may be image unit length, width, location in the document, font, typeface, cross-section, the number of ascenders, the number of descenders, the average pixel density, the length of the top line contour, the length of the base contour, the location of image units with respect to neighboring image units, vertical position, horizontal inter-image unit spacing, and so forth. The classifier comparison can be a comparison with classifiers of image units of words in a reference table, or with classifiers of other image units in the document. Equivalent classes of image units can be generated, from which word frequency and significance can be determined. The image units can be determined by creating bounding boxes about identifiable segments or extractable units of the image, and can contain a word, a phrase, a letter, a number, a character, a glyph or the like.
