Abstract: A job ticket generating system for a printing system is provided. The job ticket generating system includes a user interface having a display screen and a job ticket displayed on the user interface. The job ticket includes an original user feedback image, an electronically based scale settable in a plurality of positions, and an image processing subsystem for altering an appearance of the user feedback image in response to a change in the electronically based scale—the electronically based scale is set to one of the plurality of positions. The job ticket generating system further includes a library of masks with one of the masks being selected from the library of masks based on the one of the plurality of positions set with the electronically based scaled. In practice, the image processing subsystem applies the selected mask to the original user feedback so as to obtain an altered user feedback image whose appearance is changed relative to the original user feedback image.

Abstract: A method for matching documents based on spatial layout of regions based on a shape similarity model for detecting similarity between general 2D objects. The method uses the shape similarity model to determine if two documents are similar by logical region generation in which logical regions are automatically derived from information in the documents to be matched, region correspondence, in which a correspondence is established between the regions on the documents, pose computation in which the individual transforms relating corresponding regions are recovered, and pose verification in which the extent of spatial similarity is measured by projecting one document onto the other using the computed pose parameters.

Abstract: A method and system of recognizing handwritten words in scanned documents, wherein by processing a document containing handwriting, features for word localization are extracted from handwritten words contained in said document through basis points taken from a single curve of text lines. The method is independent of page orientation, and does not assume that the individual lines of handwritten text are parallel, and the method does not require that word regions be aligned with text line orientation wherein intra-word statistics are derived from sample pages rather than using a fixed threshold. The method has applications in digital libraries, handwriting tokenization, document management and OCR systems.

Abstract: A method for generating forms using halftones along with a set of low-complexity image processing steps to extract the characters for recognition. The method exploits texture differences between character strokes and halftoned boxes or text fields. Form frames are rendered as black and white halftones and characters are extracted by exploiting differences in texture between the frames and the character strokes. A sequence of simple image processing operations, easily done in hardware, eliminates the frames while leaving the characters intact. Halftones, giving the appearance of a light color as in the dropout-color method, are easily produced by page description languages; thus, blank and filled-in forms can be scanned, printed, stored and photocopied at low cost.

Abstract: A method for use with a printing system of a type in which one or more clients communicate with a plurality of printers by way of a network and print server is provided. The print server includes a communications layer with a plurality of connectivity modules, and each of the connectivity modules communicates with at least one of the plurality of printers. The method includes the steps of generating a document processing function call in the print server, in response to a request from one of the one or more clients, and selecting one of the plurality of connectivity modules. In turn, the document processing function call is transmitted to the selected one of the plurality of connectivity modules; and, in response to analyzing the document processing function call with the communications interface, a set of information is obtained with the selected connectivity module.

Abstract: A method for matching objects based on spatial layout of regions based on a shape similarity model for detecting similarity between general 2D objects. The method uses the shape similarity model to determine if two objects are similar by logical region generation in which logical regions are automatically derived from information in the objects to be matched, region correspondence, in which a correspondence is established between the regions on the objects, pose computation in which the individual transforms relating corresponding regions are recovered, and pose verification in which the extent of spatial similarity is measured by projecting one document onto the other using the computed pose parameters. The method of the invention can be carried out in a microprocessor-based system capable of being programmed to carry out the method of the invention.

Abstract: A printing system in which one or more clients communicate with a plurality of printers by way of a print server, whose architecture is characterized by a plurality of layers, is provided. In practice, one of the plurality of layers receives a request from one of the one or more clients and the request designates an operation to be performed with respect to one of the plurality of printers. The printing system includes an application layer, communicating with the one of the plurality of layers, for developing a command expression based on the request received by the one or the plurality of layers, and a communications interface including a first connectivity module and a second connectivity module, with the first connectivity module communicating with a first one of the plurality of printers and the second connectivity module communicating with a second one of the plurality of printers.
