Ink strokes of cursive writing are segmented to make the cursive writing more like print writing, particularly with respect to the number of strokes of a character. A stroke-segmentation module first finds the local extrema points on a stroke of input ink. Then the local extrema points are stepped through, two (or three) at a time. The stroke-segmentation module may compare the three (or four) ink segments that are adjacent to the two (or three) local extrema points to a set of predefined stroke-segmentation patterns to find a closest matching pattern. Strokes are then segmented based on a stroke-segmentation rule that corresponds to the closest matching pattern. Additional stroke segmentation may be performed based on the change of curvature of the segmented ink strokes. Then, a character-recognition module performs character recognition processing by comparing the segmented ink strokes to prototype samples at least some of which have been similarly segmented.

The present invention features a playing card shuffling device, which through the use of a small image capturing means, captures an image of the face value of each card and stores the image in memory. This image is sorted in the format of a bitmap image. The operator of the machine would be able to recall through the use of a key pad, the images of the cards that comprised the individual hands in the previous game. This feature allows for verification of a winning hand after a game has been completed. Thereby, a quick recheck of hands before paying a winning hand is performed. The face value of each card is determined by character recognition software. These card values would be stored in memory for archival access for use in monitoring the randomness of the game and determining the number of winning hands.

A method for providing access to documents and data files that are inherently valuable, and also documents that contain sensitive information, is configured with robust user identification and document control capabilities and facilitates document submission by, for or on behalf of a user who perhaps is the subject of the document. The document is processed, optionally character recognized and steganographically marked, and is stored in a fixed format together with descriptive identifiers and database indexing values to facilitate control and searching. The level of security encourages users to entrust documents to storage and the system is programmed to control disclosure of documents (or parts of them) according to the user's dictates. Correspondingly strict user identification and document controls apply to those who log on for purposes of document review or serve as authenticators. The result is a virtual safe depository for documents that enables documents to be reviewed when necessary with reduced risk of misuse, for example by inadvertent disclosure to identity thieves and others.

Submenus of a perimeter menu may also be perimeter menus and the location of a submenu option may be foretold by the appearance of its parent menu option. Menu options may be ideographs sharing a sound, a structure or another characteristic. Ideographs, which may be homophones of one another, may be associated with colored indicating regions and selection of an ideograph may be made by speaking the name of the associated color.

A phishing detection agent is provided. In one embodiment, a user's browser includes a plug-in application or agent that may capture a visual record of a webpage and, with a cached copy of known, authentic websites provided to it via periodic updates, perform a series of image comparison functions to determine if the suspected website is attempting to deceive the user.

Embodiments herein provide/acquire a document in electronic form (e.g., by receiving, copying, retrieving from storage, scanning combined with optical character recognition, etc.) and receive user input regarding visual impairment. In response to one or more levels of user visual impairment, embodiments herein automatically change (for example, immediately after scanning text) an appearance of the document, without requiring any user input, other than the visual impairment input. More specifically, when changing the appearance of the document, embodiments herein can increase the size of characters in the document, change the contrast or coloring of the text and/or background, and provide text-to-speech conversion of the document, thereby (in one embodiment) producing audio output of the text-to-speech conversion in coordination with a corresponding portion of the document being displayed. When changing the appearance of the document, embodiments herein also reformat the document (e.g., around graphic elements) to accommodate the increased size of the characters.

An automated analysis method and tool for a digitally imaged financial item can digitally recognize a plurality of characters across an area of a digital image containing character indicia at predetermined positions in the area and also possibly containing non-character indicia in the area. This finds exemplification in an automated check processing method and check sorting system in which a check's MICR line that has been read and interpreted as invalid can be digitally analyzed, via a digital image of the check, to identify MICR characters that could not be validly read or interpreted by the conventional MICR processing equipment. This includes digitally applying character recognition processing to an invalidated MICR line in a digital image of the financial item (e.g., a check). Previously invalidated MICR line data can then be corrected.

A plurality of inputs are received from the first payer device that assign the plurality of items to a first payer and at least one second payer to generate a first secondary bill and at least one second secondary bill. Each at least one second secondary bill is then sent to a respective second payer device, and payments are sent for the first secondary bill from the first payer device and each at least one secondary bill from the respective second payer device. An image of a physical bill may be taken by the first payer device and optical character recognition may be performed on the image to produce the primary bill that is displayed on the display of a first payer device.

A memory circuit for an Aho-Corasick type character recognition automaton uses a node tree for recognizing predetermined strings of characters in an incoming data stream. The recognization is based upon successive transitions in the node tree stored in memory in which each node corresponds to a recognized sequence of a character string. At least part of the nodes are related to a consecutive node by a valid transition, from an initial state to terminal states, with each one corresponding to a recognized character string This memory circuit includes first sets of consecutive memory addresses defining respectively strings of consecutive nodes accessible sequentially during successive transitions to a terminal state, and second sets of memory addresses defining multiple nodes each pointing to several states.

The invention also includes concatenating the altered characters into a character string to be rendered to a user as a test. The character string may be altered to further inhibit computerized character recognition. Other aspects of the invention are directed to computer-readable media for use with the methods.

A system and method for computing confidence in an output of a text recognition system includes performing character recognition on an input text image with a text recognition system to generate a candidate string of characters. A first representation is generated, based on the candidate string of characters, and a second representation is generated based on the input text image. A confidence in the candidate string of characters is computed based on a computed similarity between the first and second representations in a common embedding space.

Accurately detection of logos in media content on media presentation devices is addressed. Logos and products are detected in media content produced in retail deployments using a camera. Logo recognition uses saliency analysis, segmentation techniques, and stroke analysis to segment likely logo regions. Logo recognition may suitably employ feature extraction, signature representation, and logo matching. These three approaches make use of neural network based classification and optical character recognition (OCR). One method for OCR recognizes individual characters then performs string matching. Another OCR method uses segment level character recognition with N-gram matching. Synthetic image generation for training of a neural net classifier and utilizing transfer learning features of neural networks are employed to support fast addition of new logos for recognition.
