    • Techniques for providing camera based code reading are disclosed. In some aspects, a camera-readable code is generated which may be read by a code reading device. The code reading device may capture an image of the code, process the image, and decode the code. The code includes symbols arranged to form a pattern. According to one or more embodiments, an image with the code is cropped to remove extraneous information. The code image is manipulated by exact binary segmentation to remove background information from the code. The code is oriented to a grid using an interval value defined between the symbols. The symbols are decoded by comparing unique aspects of the symbols using a statistical analysis. The decoded symbols may be converted to a message for a user or be used for other purposes.
    • 公开了用于提供基于相机的代码读取的技术。 在一些方面,生成可由代码读取装置读取的相机可读代码。 代码读取装置可以捕获代码的图像,处理图像并对代码进行解码。 该代码包括排列成形成图案的符号。 根据一个或多个实施例,裁剪具有代码的图像以去除无关信息。 代码图像由精确的二进制分割操作,以从代码中移除背景信息。 代码使用在符号之间定义的间隔值定向到网格。 通过使用统计分析比较符号的唯一方面来对符号进行解码。 解码的符号可以被转换成用户的消息或用于其他目的。

    • Disclosed embodiments of the invention relate to analyzing document images, which contain positionally encoded information, such as a maze-pattern watermark, and labeling the images based on a degree to which the document's content, such as text, occludes the position-encoding information. Depending on the degree of such occlusion, it may not be possible to extract enough position-encoding bits from a camera-captured image of the document to determine the camera-captured image's location within the document. An analysis-and-labeling module receives, as input, image data output by an image-generation-and-capturing module and off-line training data; performs analysis-and-labeling processing; and outputs image-label information. The results of document-analysis-and-labeling processing may be used for efficiently determining a location of a camera-captured image within a positionally encoded document.
    • 本发明的公开的实施例涉及分析包含诸如迷宫图案水印的位置编码信息的文档图像,并且基于文档的内容(例如文本)封闭位置编码信息的程度来标记图像。 根据这种遮挡的程度,可能无法从文档的摄像机拍摄图像中提取足够的位置编码位,以确定摄像机捕获的图像在文档内的位置。 分析标签模块接收由图像生成和捕获模块输出的图像数据和离线训练数据作为输入; 执行分析和标签处理; 并输出图像标签信息。 文档分析和标签处理的结果可用于有效地确定位置编码的文档内的相机拍摄图像的位置。

    • Computer-readable media having computer-executable instructions and apparatuses categorize documents or corpus of documents. A Tensor Space Model (TSM), which models the text by a higher-order tensor, represents a document or a corpus of documents. Supported by techniques of multilinear algebra, TSM provides a framework for analyzing the multifactor structures. TSM is further supported by operations and presented tools, such as the High-Order Singular Value Decomposition (HOSVD) for a reduction of the dimensions of the higher-order tensor. The dimensionally reduced tensor is compared with tensors that represent possible categories. Consequently, a category is selected for the document or corpus of documents. Experimental results on the dataset for 20 Newsgroups suggest that TSM is advantageous to a Vector Space Model (VSM) for text classification.
    • 具有计算机可执行指令和设备的计算机可读介质将文档或语料库分类。 张量空间模型(TSM),其通过高阶张量对文本进行建模,表示文档或文档语料库。 由多线代数技术支持,TSM为多因素结构分析提供了框架。 TSM还受到操作和提出的工具的支持,例如用于降低高阶张量尺寸的高阶奇异值分解(HOSVD)。 将尺寸减小的张量与表示可能类别的张量进行比较。 因此,文档或文档的语料库选择一个类别。 20个新闻组的数据集的实验结果表明,TSM对于文本分类的向量空间模型(VSM)是有利的。

    • An input method and apparatus is provided for use in various computer and mobile devices. The input device utilizes a rotating dial in which four arrows printed on the dial are rotated to select characters that are fixed along the circumference of a circle. The characters are divided into various zones. The zones are utilized to encode various letters and numbers. Additionally the zones may be utilized for editing and control functions. The dial may be freely rotated. Pressing any arrow inputs the character that the arrow points to on the dial. The input device and method may encode Asian language characters according to a set of encoding rules.
