摘要： Recorded video is accessed from printed notes or summaries derived from the video. Summaries may be created automatically by analyzing the recorded video, and annotations are made by a user on a device for note-taking with digital ink and video. The notes and/or summaries are printed along with data glyphs that provide time based indexes or offsets into the recorded video. The indexes or offsets are retrieved by scanning the glyph on the printout. The glyph information can be embedded in the printouts in many ways. One method is to associate block glyphs with annotations or images on the printed pages. Another method is to provide an address carpet in an annotated timeline. Yet another method is to provide a two-dimensional address carpet with X-Y position mapped to time which can be used to provide selected access to the video. The accessed video may be played back on the note-taking device on a pen computer, or on a summary interface on a Web browser-type device.
摘要翻译：录制的视频可从打印的笔记或从视频派生的摘要访问。可以通过分析录制的视频来自动创建摘要，并且用户在设备上进行注释，以便使用数字墨水和视频进行笔记。笔记和/或摘要与将记录的视频中提供基于时间的索引或偏移量的数据字形一起打印。通过扫描打印输出上的字形来检索索引或偏移量。字形信息可以以许多方式嵌入到打印输出中。一种方法是将块字形与印刷页面上的注释或图像相关联。另一种方法是在注释时间线中提供地址毯。另一种方法是提供二维地址毯，其中X-Y位置映射到时间，其可以用于提供对视频的选择的访问。所访问的视频可以在笔式计算机上的笔记本设备上或者在Web浏览器型设备的汇总接口上播放。

摘要： A mouse incorporating a camera captures an image of embedded data from a substrate under the mouse. The embedded data in the image is decoded to determine address or location information coded in the embedded data. Based on the decoded information and other user input signals, such as mouse button selection signals, the computer executes operations. The mouse also has a display controlled by the computer for providing visual feedback to a user. The display might generate an image of the substrate area under the mouse, making it appear to the user as if they are looking through the mouse directly onto the substrate. The display may also generate visual feedback regarding operations occurring in the computer, such as selection or other computer operations.

摘要： An angular orientation of a lattice image pattern is found by forming a composite image of superimposed portions of a lattice image by aligning centroids of a lattice element in each portion, and determining a lattice axis from a line fit through centroids of lattice elements in the composite image. The composite image is formed by selecting a seed pixel, finding a local minimum near the seed pixel and then finding a centroid based on the local minimum. From the centroid, it is determined whether the glyph centroid has sufficient contrast to be included in the composite image. The composite image is formed by superimposing subsamples of the lattice image based on glyph centroids. The composite image is then analyzed to determine a lattice axis through centroids in the composite image, and determining a quadrant image based on the lattice axis.

摘要： An optically readable record for storing encoded information comprises (1) a recording medium, (2) a self-clocking data code for encoding the information, with this data code being composed of glyphs that are written in a two dimensional code field on the recording medium on centers that are spatially distributed in nominal accordance with a predetermined spatial formatting rule. The glyphs are defined by respective symbols that are selected from a finite set of optically discriminable symbols to encode the information. Further, there is at least one additional glyph pattern that is written on the recording medium in nominal accordance with the aforementioned spatial formatting rule, with this additional code pattern being discriminable from the data code and being selected to disambiguate data codes that are rotated and/or reflected.

摘要： A self-clocking glyph code is composed of data glyphs which encode logically ordered data values, together with one or more multi-glyph synchronization code patterns. Each of the synchronization code patterns is distinguishable from the data glyphs, but the synchronization code pattern or patterns provide an explicit spatial reference for the data glyphs. To this end, the glyphs of the synchronization code pattern or patterns are written on the recording medium in accordance with the same spatial formatting rule as the data glyphs, plus at least one additional formatting rule that establishes a predetermined geometric relationship between the glyphs of the synchronization code pattern or patterns and corresponding ones of the spatially formatted data glyphs, such that the logical order of at least a significant number (>>1) of the data glyphs is inferable from the synchronization code pattern or patterns. Preferably, each of the synchronization code patterns is composed of glyphs that are selected from the same finite symbol set as the data glyphs, so the synchronization code pattern or patterns typically are defined by glyph patterns that have a suitably high statistical probability of being unique with respect to any pattern of data glyphs.
摘要翻译：自我时钟字形代码由数据字形组成，数字字形与一个或多个多字形同步码模式一起编码逻辑排序的数据值。每个同步码模式与数据字形区分开，但同步码模式或模式为数据字形提供了明确的空间参考。为此，同步码图案或图案的字形根据与数据字形相同的空间格式规则写入记录介质，加上至少一个额外的格式化规则，其在同步码模式或模式以及对应的空间格式化数据字形，从而可以从同步码模式或模式推断数据字形的至少大数量（>> 1）的逻辑顺序。优选地，每个同步代码模式由从与数据字形相同的有限符号集中选择的字形组成，因此同步码模式或模式通常由具有适当高的统计概率的字形模式定义，尊重任何模式的数据字形。

摘要： A system and computer-implemented method for calibrating a document processing device from a composite document is disclosed. A composite document including human-readable content and machine-readable code marks is input into a document processing device. The machine-readable code marks are decoded to identify at least one spatial pointer including at least one nominal property of at least a portion of the human-readable content. The at least one nominal property is compared to an input property of the human-readable content. One or more distortions in the input property compared to the at least one nominal property are identified. The document processing device is calibrated based on the identified distortions.

摘要： A method and apparatus for quasi-reprographically replicating a source document. The source document is digitized, appropriate locations for embedded code are detected, and any embedded code located in the digitized document along with the detected locations are forwarded to a decoder. The decoder forwards the decoded information to a control unit which processes this information and forwards it to a encoder whereafter it is inserted in the digitized document. The hardcopy replication of the source document being substantially visually identical to the source document, even though new or additional embedded machine-readable data has been added or existing data has been changed. The process occurs without intervention by an operator and without knowledge of the operator producing the replicated documents.

摘要： A method of achieving optimum optical contrast for detecting registration marks in a multicolor electrophotographic printing machine. The reflectivity of the image carrying member which is usually an intermediate transfer belt is determined. The reflectivity of each of the toners is then determined. If one of the toners has a contrasting reflectivity, while the remaining toners do not contrast then a uniform field of the contrasting toner is imaged and developed and the registration marks for the other toner colors are then developed on top of the uniform field. A void in the field in the shape of the other toner marks is used as the registration mark for the contrasting toner. If all of the toners have a contrasting reflectivity with the belt, the registration marks are imaged and developed directly on the belt.
