G06V 40/30
Definition
Diese Klassifikationsstelle umfasst:(Für diese Definition ist die deutsche Übersetzung noch nicht abgeschlossen)
Acquisition, pre-processing, feature extraction, and classification of handwritten signatures and handwritten text input to identify the writer.
The processing may be based on a bit map image showing the signature (called static or offline signature recognition) or a signal representing the position, velocity, acceleration, or pressure of the writing tip (called dynamic or online signature recognition).
Examples
Handwriting input using a grid defined on the screen of a mobile phone
Transforming a signature to a consistent angle of inclination for recognition purposes
Temporal analysis of a pen stroke for signature encoding
