摘要： Pre-processing techniques for processing an image to improve the distinctiveness of an information pattern captured in the image before the information pattern is analyzed in a decoding process. The brightness of an image first is normalized by dividing the image into blocks of areas, such as pixels. A brightness distribution value then is determined for each area of the image by fitting the brightness of its surrounding blocks using bilinear interpolation and extrapolation, and a normalized brightness value for each area can then be obtained by dividing the original brightness value by the brightness distribution value. Next, masks are created to distinguish the information pattern from content captured in the image. The masks may be generated based upon contrast differences between the brightness of pixels representing the information pattern, the brightness of pixels representing content, and the brightness of pixels representing the background of the writing medium.

A surface-type-identification module accepts as input both types of images and identifies, for a particular image, the type of surface from which the image was captured. A display-surface-preprocessing module preprocesses the at least one embedded-interaction-code image captured from a display surface other than a printed document. A printed-document-preprocessing module preprocesses the at least one embedded-interaction-code images captured from a printed document. An embedded-interaction-code-processing module outputs location information for at least one of the at least one image captured from a printed document and the at least one image captured from a display surface other than a printed document.

摘要： X-y positions of a digital pen's tip may be determined by using a calibration parameter to map the x-y positions of the respective centers of images captured by the pen's camera. The calibration parameter may be generated by iteratively calculating estimates of the calibration parameter. Calibration input data may be produced by a user placing the pen tip in a fixed location on a surface, which may be a positionally encoded medium, such as paper, and then rotating the pen and/or moving the opposite end of the pen in various directions to capture multiple images for use in generating the calibration parameter. A user may perform such a calibration procedure without the need for complicated calibration equipment typically used in connection with conventional calibration techniques.

摘要： In accordance with embodiments of the invention, global metadata, such as a document identifier, which may be a globally unique identifier, is embedded into an embedded interactive code document by combining a first m-array and a plurality of copies of the first m-array to generate a combined m-array with encoded global metadata such that respective start positions (xd,yd)i of the plurality of copies of the first m-array in the combined m-array are each shifted, by respective amounts that are based on respective portions of the global metadata, relative to a start position of the first m-array in the combined m-array. Global metadata may be decoded from the combined m-array by determining the respective amounts by which the plurality of copies of the first m-array are shifted, relative to the first m-array, in the combined m-array and by combining the respective amounts to produce a decoded value of the global metadata.

摘要： Systems and methods that determine a path of a pen tip as the pen tip is moved across a document are described. The document is watermarked with a maze pattern from which encoded position information is determined. A sequence of images is captured by a camera that is located in a pen. The path of the pen tip is determined by decoding the associated maze pattern and by matching the captured images with document images. If the position coordinates of any frame that is associated with a stroke cannot be determined from m-array decoding, the frames are transformed and then matched with an area of a document image. Once the position coordinates of at least one frame is determined, the position coordinates of other frames are determined by matching the frames in a neighboring area.

摘要： An efficient technique is disclosed for determining a portion of a document corresponding to a captured image. When a user employs a pen to create a stroke in a document, images of the document are captured by a camera mounted on the pen. While the location of some of the images will be determined from, for example, an analysis of a pattern on the document that is captured by the image or a pixel-by-pixel comparison of the image with the document, the location of other images will be determined by segmenting the sequence of images into groups that correspond to the shape of the stroke. Information relating to located images in a segment can then be employed to determine the position of unlocated images in the segment. For example, a document search region for an unlocated image can be established based upon the position of a previous located image and a maximum velocity or acceleration of the pen. The rotation and scale of the unlocated image are estimated as the same of the located image, and the unlocated image is warped using the rotation and scale. A pixel-by-pixel comparison can then be made between the warped unlocated image and the document search region. Further, if the warped unlocated image is matched successfully, the transform parameters of the image can be further refined.
摘要翻译：公开了一种用于确定与捕获图像相对应的文档的一部分的有效技术。当用户使用笔在文档中创建笔画时，文档的图像由安装在笔上的相机捕获。虽然一些图像的位置将通过例如对由图像捕获的文档上的图案或图像与文档的逐像素比较的分析来确定其他图像的位置将通过将图像序列分割成对应于笔画形状的组来确定。然后可以使用与片段中的定位图像相关的信息来确定片段中未定位图像的位置。例如，可以基于先前定位的图像的位置和笔的最大速度或加速度来建立用于未定位图像的文档搜索区域。未定位图像的旋转和缩放被估计为与所定位的图像相同，并且使用旋转和刻度来扭曲未定位的图像。然后可以在翘曲的未定位图像和文档搜索区域之间进行逐像素比较。此外，如果翘曲的未定位图像成功匹配，则可以进一步改进图像的变换参数。

摘要： Processes and apparatuses print documents containing embedded interactive code (EIC) information by the use of custom postscript commands that are printer independent, with little overhead when printing, smaller print file size, and faster print times. In order to determine the postscript commands, the EIC array may be represented as a bit for every point, as EIC symbols in which each kind of EIC symbol is a glyph of a font, or as graphics procedures. The postscript approach may be selected based on memory and printing time requirements.

摘要： Described is a technology by which online recognition of handwritten input data is combined with offline recognition and processing to obtain a combined recognition result. In general, the combination improves overall recognition accuracy. In one aspect, online and offline recognition is separately performed to obtain online and offline character-level recognition scores for candidates (hypotheses). A statistical analysis-based combination algorithm, an AdaBoost algorithm, and/or a neural network-based combination may determine a combination function to combine the scores to produce a result set of one or more results. Online and offline radical-level recognition may be performed. For example, a HMM recognizer may generate online radical scores used to build a radical graph, which is then rescored using the offline radical recognition scores. Paths in the rescored graph are then searched to provide the combined recognition result, e.g., corresponding to the path with the highest score.
