摘要： The subject invention leverages a scalable character glyph hash table to provide an efficient means to identify print characters where the character glyphs are identical over independent presentation. The hash table allows for quick determinations of glyph meta data as, for example, a pre-filter to traditional OCR techniques. The hash table can be trained for a particular environment, user, language, character set (e.g., alphabet), document type, and/or specific document and the like. This permits substantial flexibility and increases in speed in identifying unknown glyphs. The hash table itself can be composed of single or multiple tables that have a specific optimization purpose. In one instance of the subject invention, traditional OCR techniques can be utilized to update the hash tables as needed based on glyph frequency. This keeps the hash tables from growing by limiting updates that reduce its performance, while adding frequently determined glyphs to increase the pre-filter performance.
摘要翻译：本发明利用可缩放的字符字形哈希表来提供用于识别字符字形在独立呈现上相同的打印字符的有效手段。哈希表允许快速确定字形元数据，例如，对传统的OCR技术进行预过滤。可以针对特定环境，用户，语言，字符集（例如字母表），文档类型和/或特定文档等对哈希表进行训练。这允许在识别未知字形中的基本灵活性和速度增加。散列表本身可以由具有特定优化目的的单个或多个表组成。在本发明的一个实例中，可以使用传统的OCR技术来根据字形频率根据需要来更新哈希表。这样可以通过限制降低性能的更新来限制哈希表的增长，同时添加经常确定的字形以增加预过滤器的性能。

摘要： The present invention provides a unique system and method that facilitates obtaining high performance and more secure HIPs. More specifically, the HIPs can be generated in part by caching pre-rendered characters and/or pre-rendered arcs as bitmaps in binary form and then selecting any number of the characters and/or arcs randomly to form a HIP sequence. The warp field can be pre-computed and converted to integers in binary form and can include a plurality of sub-regions. The warp field can be cached as well. Any one sub-region can be retrieved from the warp field cache and mapped to the HIP sequence to warp the HIP. Thus, the pre-computed warp field can be used to warp multiple HIP sequences. The warping can occur in binary form and at a high resolution to mitigate reverse engineering. Following, the warped HIP sequence can be down-sampled and texture and/or color can be added as well to improve its appearance.
摘要翻译：本发明提供了一种独特的系统和方法，其有助于获得高性能和更安全的HIP。更具体地说，可以部分地通过将预渲染字符和/或预渲染的弧缓存为二进制形式的位图，然后随机选择任意数量的字符和/或弧形成HIP序列，来部分地生成HIP。翘曲域可以被预先计算并转换成二进制形式的整数，并且可以包括多个子区域。翘曲区也可以缓存。任何一个子区域都可以从warp域高速缓存中检索，并映射到HIP序列以扭曲HIP。因此，可以使用预先计算的翘曲场来扭曲多个HIP序列。翘曲可以以二进制形式和高分辨率发生，以减轻逆向工程。以下，翘曲的HIP序列可以进行下采样，并且可以添加纹理和/或颜色以改善其外观。

摘要： A method and system for implementing character recognition is described herein. An input character is received. The input character is composed of one or more logical structures in a particular layout. The layout of the one or more logical structures is identified. One or more of a plurality of classifiers are selected based on the layout of the one or more logical structures in the input character. The entire character is input into the selected classifiers. The selected classifiers classify the logical structures. The outputs from the selected classifiers are then combined to form an output character vector.

摘要： The subject invention provides a unique system and method that facilitates creating HIP challenges (HIPs) that can be readily segmented and solved by human users but that are too difficult for non-human users. More specifically, the system and method utilize a variety of unique alteration techniques that are segmentation-based. For example, the system and method employ thicker arcs or occlusions that do not intersect characters already placed in the HIP. The thickness of the arc can be measured or determined by the thickness of the characters in the HIP. In addition to increasing the thickness, the arcs can be lengthened because longer arcs tend to resemble pieces of characters and may be harder to erode. Usability maps can be generated and used to selectively place clutter or occlusions and to selectively warp characters or the character sequence to facilitate human recognition of the characters.
摘要翻译：本发明提供了一种独特的系统和方法，其有助于创建可以容易地由人类用户分割和解决的HIP挑战（HIP），但是对于非人类用户来说太难了。更具体地说，该系统和方法利用了基于分段的各种独特的改变技术。例如，系统和方法采用较大的弧或闭合不与HIP中已经放置的字符相交。电弧的厚度可以通过HIP中字符的厚度来测量或确定。除了增加厚度之外，弧可以延长，因为较长的弧往往类似于一些字符，并且可能难以侵蚀。可用性图可以被生成并用于选择性地放置杂乱或闭塞，并且选择性地扭曲字符或字符序列以促进人类对字符的识别。

摘要： Systems and methods are described that facilitate performing feature extraction across multiple received input features to reduce computational overhead associated with feature processing related to, for instance, optical character recognition. Input feature information can be unfolded and concatenated to generate an aggregated input matrix, which can be convolved with a kernel matrix to produce output feature information for multiple output features concurrently.

摘要： A printer, scanner device and methods for using same are described herein. A printer device may include a dedicated input that, when actuated, generates and sends a request to a computer for known data or a predetermined print job, e.g., schedule information from a personal information management (PIM) application. A scanner device may include another dedicated input that, when actuated, automatically scans a document fed to the device by the user and sends the scanned image to IM (or other) software on a computer, bypassing the need to manipulate the scanned image using scanner software. The device may be used with printed metapaper, which includes a barcode or other indicia identifying the metapaper and corresponds to a stored template image of the metapaper. When the metapaper is rescanned, the scan can be compared to the stored template information to identify changes and synchronize the changes with the IM software.

摘要： An approach for identifying suspect network sites in a network environment entails using one or more malware analysis modules to identify distribution sites that host malicious content and/or benign content. The approach then uses a linking analysis module to identify landing sites that are linked to the distribution sites. These linked sites are identified as suspect sites for further analysis. This analysis can be characterized as “bottom up” because it is initiated by the detection of potentially problematic distribution sites. The approach can also perform linking analysis to identify a suspect network site based on a number of alternating paths between that network site and a set of distribution sites that are known to host malicious content. The approach can also train a classifier module to predict whether an unknown landing site is a malicious landing site or a benign landing site.
