摘要： The user communicates through a digitizing writing surface with the audio/video control apparatus. An on-screen display is generated, providing the user with a user environment in which a wide range of different tasks and functions can be performed. The digitizing writing surface can be incorporated into a hand-held remote control unit and the audio/video control apparatus may likewise be incorporated into existing home entertainment or computer equipment. By tapping on the writing surface a command bar is presented on the screen, allowing the user to select among various functions. Included in these functions is an on-screen programming feature, allowing the user to select programs for viewing or recording by entry of user-drawn annotations or commands via the writing surface.

摘要： The document browser for electronic filing systems supports pen-based markup and annotation. The user may electronically write notes anywhere on a page and then later search for those notes using the approximate ink matching (AIM) technique. The technique segments the user-drawn strokes, extracts and vector quantizes features contained in those strokes. An edit distance comparison technique is used to query the database, rendering the system capable of performing approximate or partial matches to achieve fuzzy search capability.

摘要： A system and method for storage and retrieval of pictographic images as computer file names. Upon generation of an input image, the computer saves the image and extracted spatial and temporal information about the generation of the image. The extracted information can be accessed for comparison, ordering and retrieving of stored pictographic file names and subsequent display to the user. Final selection of the desired name is performed visually by the user while viewing a display of the ordered file names via a document browser.

摘要： Inventive two-dimensional barcodes, each having encoded digital information in a bitmap representing preferably randomized encoded data bits, are printed onto a printed medium. Preferably, error correction codes are added to the digital information to ensure that the decoding process accurately reproduce the digital information. In one embodiment, the bitmap may further include “anchor” bits in each corner, which are used as part of the skew estimation and deskewing processes during decoding. In a second embodiment, no “anchor” bits are required. The encoded digital information is mapped into the two-dimensional barcode in such a way as to minimize the errors caused by damage to particular rows and/or columns, for example, row damage caused by faxing the printed barcode. To extract the encoded digital information from the printed medium, the printed medium is scanned, then the bitmap is located within the printed medium. The skew of the bitmap, if any, is determined, and the bitmap is deskewed if necessary. The bitmap is then cropped, and the randomized digital information is read from the bitmap. The digital information is derandomized and any error correction codes are removed, in the process correcting and/or recording any errors discovered, thereby reproducing the original encoded digital information.

摘要： A method for recognizing a table structure from delineated table region in an electronic document using hierarchical clustering of data strings. The cluster groupings are segregated effectively using the distances from a positional vector associated with words and groups of words rather than a minimum number of blank spaces between words. Once a data tree of the hierarchical clusterings is constructed, the tree is scanned downward from the root to find appropriate column boundaries using a columnization algorithm. Then using successive heuristic algorithms, determine column and row headers and row boundaries.

摘要： A method of managing storage in a document image database using document analysis to partition documents into logical regions and modified by reducing storage size of the regions using different reduction means according to various storage preference rules. Storage preference rules are intended to maintain high quality representations of important document information while reducing storage requirements at the expense of lesser important aspects of the document. In particular, the different reduction means applied to stored document images includes reducing sampling depth, reducing sampling resolution based on minimum font size, utilizing lossy and lossless compression schemes and discarding unimportant regions of document image. Over time, document analysis and modification can be repeated to further reduce the storage size of previously stored data files.

摘要： The method and apparatus enables any user to search for logos in document images stored in a bitmap format. The search efficiently compares bitmap or image data by extracting a series of connected components. These connected components are grouped according to region where each region may be a potential logo. Shape and density parameters of a region are determined and compared to the parameters of the stored logo image. If a region is successfully matched then that region is aligned and scaled to the corresponding stored logo image. Thereafter, a bitwise comparison is then performed between the scaled and aligned region and the logo image. A match score is assigned to each region along with other pertinent information about the region, and is stored in a ranked logo list database. The ranked logo list database represents a list of logos found in the document image.
摘要翻译：该方法和装置使得任何用户能够在以位图格式存储的文档图像中搜索标识。搜索通过提取一系列连接的组件来有效地比较位图或图像数据。这些连接的组件根据每个区域可能是潜在标志的区域进行分组。确定区域的形状和密度参数，并与存储的标志图像的参数进行比较。如果一个区域成功匹配，那么该区域对齐并缩放到相应的存储的标志图像。此后，在缩放和对准的区域和标志图像之间进行按位比较。将匹配得分与其他有关区域的相关信息一起分配给每个区域，并存储在排名标记列表数据库中。排名的商标列表数据库代表在文档图像中找到的徽标列表。

摘要： Apparatus and a method for comparing an electronic handwritten pattern to a stored string are provided. The string includes a group of portions, each having at least one stroke. Movement of a stylus forms the pattern, and a sequence of strokes is generated. Each stroke represents a stylus movement within a predetermined alphabet. The sequence of strokes has a plurality of portions. A linear systolic array processor determines an edit distance between the string and the pattern. The processor compares a first portion of the string to a first portion of the pattern. A plurality of edit distance components are generated based on the comparison. Each component corresponds to a different set of operations that transforms the first portion of the stored string into the first portion of the pattern. The components are calculated based on a further comparison between additional portions of the stored string and the pattern. The component which has a minimum value is selected. The comparison is performed between each respective portion of the pattern and the corresponding portion of the stored string. The total edit distance is based on the component selected during a last comparison between a last portion of the stored string and a last portion of the pattern.
