  • Publication number: 20050008221
    Abstract: A printing system includes embedded functionality for performing media content recognition and processing. Based on the results of the content recognition and processing performed on the media content, the printing system can generate a paper-based or other printed representation thereof. The printing system may further produce a corresponding electronic representation of the media content, which in combination with the printed representation can be used to view and access the media content. A printing system may also include a media renderer application having a print functionality for printing selected media content.

  • Publication number: 20040042667
    Abstract: A method and apparatus for extracting information from symbolically compressed document images. A deciphering module generates first and second text strings by deciphering respective sequences of template identifiers in first and second symbolically compressed document images. A conditional n-gram module receives the first and second text strings from the deciphering module and extracts n-gram terms therefrom based on a predicate condition. A comparison module generates a measure of similarity between the first and second symbolically compressed document images based on the n-gram terms extracted by the conditional n-gram module.

  • Publication number: 20040010527
    Abstract: An online Gaussian mixture learning model for dynamic data utilizes an adaptive learning rate schedule to achieve fast convergence while maintaining adaptability of the model after convergence. Experimental results show an unexpectedly dramatic improvement in modeling accuracy using an adaptive learning schedule.

  • Publication number: 20030126161
    Abstract: A method and apparatus for document management including assigning labels to gaps in document production. The gaps may correspond to events that caused an individual to begin and/or cease production/modification of documents. Such events can be, for example, a vacation, a business trip, a meeting, etc. The labels can be used for document retrieval purposes. In one embodiment predetermined events, either predefined or user-defined, are used to automatically label gaps in document production. In one embodiment, the invention provides links to documents that correspond to gaps in document production where the links can be used for document retrieval purposes.

  • Publication number: 20020116379
    Abstract: An apparatus and method for determining if a query document matches one or more of a plurality of documents in a database. In a coarse matching stage, a compressed file or other query document is scanned to produce a bit profile. Global statistics such as line spacing and text height are calculated from the bit profile and used to narrow the field of documents to be searched in an image database. The bit profile is cross-correlated with bit profiles of documents in the search space to identify candidates for a detailed matching stage. If multiple candidates are generated in the coarse matching stage, a set of endpoint features is extracted from the query document for detailed matching in the detailed matching stage. Endpoint features contain sufficient information for various levels of processing, including page skew and orientation estimation.
