摘要： An automatic character cell determining apparatus automatically determines the character cells within the text image of a document. A connected component generator means generates connected components from the pixels comprising the text image. An aligning device aligns skewed and warped lines to the proper image axes. A bounding box generator generates a bounding box surrounding each connected component. A character cell determining device for locating character cells including one or more connected components has a vertical splaying device and a horizontal splaying device for ensuring white spaces between lines and connected components, a vertical profile device for determining the vertical positions of a line, a splitting device for splitting ligatures of two or more connected components and a character cell generator for generating character cells grouping together one or more connected components.

摘要： An automatic language determining apparatus automatically determines the particular Asian language of the text image of a document when the gross script-type is known to be, or is determined to be, an Asian script-type. A connected component generating means generates connected components from the pixels comprising the text image. A character cell generating means generates a character cell surrounding at least one connected component. An optical density determining means determines the optical density, in absolute numbers or percentage of pixels, of the pixels within each character cell. A script feature determining means first generates a histogram, then converts, by linear discriminate analysis, the histogram to a point in a new coordinate space. A language determining means compares the determined point of the text portion in the new coordinate space to predetermined regimes in the new coordinate space corresponding to at least one Asian language to determine the particular Asian language of the text image.

摘要： An automatic language-determining apparatus automatically determines the particular European language of the text image of a document when the gross-script-type is known to be, or is determined to be, an European script-type. A word token generating means generates word tokens from the text image. A feature determining means determines the frequency of appearance of word tokens of the text portion which correspond to predetermined word tokens. A language determining means converts the determined frequency of appearance rates to a point in a new coordinate space, then determines which predetermined region of the new coordinate space the point is closes to, to determine the language of the text portion.

摘要： An automatic script determining apparatus automatically determines the gross script-type of the text image of a document. A connected component generating means generates connected components from the pixels comprising the text image. A bounding box generating means generates a bounding box surrounding each connected component. A centroid determining means determines a centroid for each bounding box. A script feature determining means determines the locations, relative to the centroid, of one or more predetermined types of features, for each bounding box. A script determining means determines a distribution of the located script features for the entire text image, and compares the determined spatial distribution to predetermined distribution for at least one script-type to determine the script type of the text image.

摘要： A first method for exact and inexact matching of documents stored in a document database includes the step of converting the documents in the database to a compacted tokenized form. A search string or search document is then converted to the compact tokenized form and compared to determine if the test string occurs in the documents of the database or whether the documents in the database correspond to the test document. A second method for inexact matching of a test document to the documents in the database includes generating sets of one or more floating point values for each document in the database and for the test document. The sets of floating point numbers for the database are then compared to the set for the test document to determine a degree of matching. A threshold value is established and each document in the database which generates a matching value closer to the test document that the threshold is considered to be an inexact match of the test document.
摘要翻译：用于精确和不精确匹配存储在文档数据库中的文档的第一种方法包括将数据库中的文档转换为压缩的标记化形式的步骤。然后将搜索字符串或搜索文档转换为紧凑的标记表单并进行比较，以确定测试字符串是否出现在数据库的文档中，或者数据库中的文档是否对应于测试文档。测试文档与数据库中的文档的不精确匹配的第二种方法包括为数据库中的每个文档和测试文档生成一个或多个浮点值的集合。然后将数据库的浮点数集合与测试文档的集合进行比较，以确定匹配程度。建立阈值，并且数据库中的每个文档生成更接近测试文档的匹配值，阈值被认为是测试文档的不精确匹配。

摘要： An automatic abstract character coding system automatically generates abstract coded characters from the text image of a document when the gross script-type is known to be, or is determined to be, a European type script. A connected component generating means generates connected components from the pixels comprising the text image. A spatial feature determining means generates a character cell surrounding one or more aligned connected component. A character-type classifying means converts the character cell to one of a plurality of abstract character codes.

摘要： An automated packaging system for automated collating, stacking and transferring long cut retail edge marker strips exiting a roll fed high speed slitter/perforator/cutter apparatus includes a series of angled and stepped baffles configured to receive the cut retail edge marking strips and allow them to fall into and accumulate in bins formed by each angled baffle and then be removed from each bin consecutively by an automated pusher acting orthogonally to the bins to move and collate the retail edge markers into a final stack collated to meet a specific store planogram requirement. An automated transfer unit moves the final stack downstream for further packaging, which may include automated banding and loading of the final stack into an empty container for shipment to the store having the specific planogram requirement.
