Abstract:
1. A computer-implemented system having a processor communicatively coupled to a memory for facilitating obtaining ink annotations from paper, comprising: a comparator that compares an initial electronic version of a document with an electronic image of an annotated version of the document to identify an ink annotation supplementing original text of the initial electronic version of the document, the ink annotation including at least one of emphasis highlighting, typewritten information, stamped information, or printed information placed over, near, or around original text; an annotation lifter that extracts the ink annotation from the electronic image and converts the ink annotation into an independent computer-usable object and assigns a document-altering command to the object based on an effect on the electronic image determined for the ink annotation; an image registration component that registers the electronic image of an annotated version of the document with the initial electronic version of the document; an image subtractor that subtracts an image of the initial electronic version of the document from the electronic image of an annotated version; a stroke joiner that joins a broken stroke of the ink annotation, the broken stroke being included in the ink annotation; and, an integrator that inserts the computer-usable object representing the ink annotation at an appropriate nonstatic anchor position within an editing version of the document.
