Abstract: A method and process provides structure recognition to a node-link diagram formed by a plurality of digital ink strokes drawn on a canvas of an electronic device by an input device. The method and process include grouping related strokes into multiple hypotheses reflecting structure interpretations of the strokes in a group. Confidence scores are computed for the multiple hypotheses based on local evidence regarding the strokes of the stroke groups and surrounding strokes. Constraints are applied among the hypotheses, and a collectively high scoring assignment of accept/reject values of the hypotheses are determined under the applied constraints. The hypotheses with collectively high scoring assignments are accepted as a representation of the node-link diagram, where structure information is provided to the strokes of the node-link diagram, making the node-link diagram electronically editable.

Abstract: A method and system provides intelligent node-link diagram creation and editing, including an electronic display device having a surface on which a writing and/or drawing canvas is provided. An input device permits writing and/or drawing of electronic ink strokes, and a computing device is in operative association with the electronic display and the input device, and has stored therein for operation in connection with actions of the input device, a user interface (UI). The UI includes a graphical user interface (GUI) module, which controls input and display of the ink strokes applied to the canvas by the input device, and a recognition module which interprets the ink strokes by performance of structure recognition operations.

Abstract: A method and process provides a selection process designed to select optimized results from a plurality of possible results represented in a search tree. A tree search is employed, wherein bounds are used to prune at least one node or branch of the search tree. A non-overlapping support constraint in conjunction with the tree search is invoked to further prune the search tree. An optimized search tree is stored into a memory, following the invoking of the non-support constraint, and the optimized search tree is employed in additional processing operations.

Abstract: A document processing system and method thereof are disclosed. The system comprises machine-readable data such as DataGlyphs and human-readable data such as rendering text of the DataGlyphs that are applied on the document. Processing devices of the system can decode document-processing instruction(s) embedded in the machine-readable data, and then optionally execute at least part of the instruction automatically. A designed stamp is also provided to generate the machine-readable data and human-readable data on the document.

Abstract: In accordance with one aspect of the present exemplary embodiment, provided is a hand-held printer system and method for printing on a target. The system includes a hand-held printer, a target position sensing system which senses a position of the target, and a hand-held printer position sensing system which senses a position of the hand-held printer relative to a printing surface of the target. A control mechanism actuates the printing of the hand-held printer based on the sensed positions.

Abstract: A method for enhancing electronic images of a document, in which the electronic images contain a background with foreground markings, includes receiving an electronic image containing pixels and assigning an initial provisional foreground/background status to the pixels. The initial foreground/background estimate is revised and a determination is made as to whether the revised foreground/background estimate is to be the final status assignment for the pixels of the image. If a final pixel status assignment has not been achieved, the estimate is again revised until a final foreground/background status is reached for the image pixels prior to creation of an output image.
