Abstract: A printing system enables the printing of enhanced documents using a semantic classification scheme. A printing system receives an image to be printed. The system classifies the image according to the semantic classification scheme and, based on this classification, performs enhancement processing on the image. Depending on the desired application, the printing system may recognize and classify any number of image types and may then perform various enhancement processing functions on the image, where the type of enhancement processing performed is based on the classification of the image.

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.

Abstract: Techniques for an iterative design process of determining a visual representation for an input media object are provided. One or more visual representations are determined from the input media object based on a set of encoding parameters. An output media object is then created from the one or more visual representations based on a set of decoding parameters. The one or more visual representations and/or the second media object may be displayed to a user. An indication indicating whether one or more visual representations and/or the second media object is acceptable or unacceptable is then received. If the one or more visual representations and/or the second media object is not acceptable, then at least one parameter in at least one of the set of encoding parameters and the set of decoding parameters may be changed. The process described above is then repeated until the one or more visual representations and the second media object is determined to be acceptable.

Abstract: Techniques for creating an output media object based on a first visual representation and a second visual representation are provided. A first visual representation is received. The first visual representation is generated based on first information determined from an input media object. A second visual representation is also received. The second visual representation is generated based on second information determined from the input media object. An output media object is then created based on the first visual representation and a second visual representation. The output media object may then be outputted or played on a device.

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.
