  • Patent number: 7664325
    Abstract: Computer-readable media having computer-executable instructions and apparatuses detect a structured handwritten object is detected in a handwritten document. A primitive structure, which is associated with a set of component objects, is formed. A candidate handwritten object is identified by detecting a corresponding logical structure. A classifier for the candidate handwritten object is determined. Consequently, the candidate handwritten object is validated from the classifier.

  • Patent number: 7657094
    Abstract: Methods and systems for converting text into natural personal handwriting are provided. One aspect relates to the training of a computer to recognize a user's handwriting style. In one embodiment, the computer receives handwriting samples of at least one character written by the user, such as the character being provided as the beginning, middle, or ending character among a plurality of other characters. Further embodiments allow for increased personalization of the handwriting. Another aspect relates to system and methods for displaying a representation of a computer user's handwriting. In one embodiment, the handwriting comprises variant shapes of letters, personalized connection style between letters, and connection parts that look pressure-sensitive. In another embodiment, characters are adjusted, such as cutting portions of the character to create a more realistic recreation and synthesis of the handwriting.

  • Patent number: 7583841
    Abstract: Computer-readable media having computer-executable instructions and apparatuses detect a table in a handwritten document. Line segments are derived from drawing strokes so that a bounding frame of a candidate table is obtained. An associated table structure is consequently recognized from the bounding frame, lines segments within the bounding frame, and their intersection points. A classifier that reflects at least one table characteristic is determined, and the candidate table is consequently validated or rejected.
