Class Information
Number: 382/122
Name: Image analysis > Applications > Personnel identification (e.g., biometrics) > Using a signature > Sensing speed or acceleration only
Description: Subject matter wherein the characteristic of the writing sample used is only speed (velocity, that is, the first derivative of the values of the pen movement) or acceleration (change in velocity, that is, the second derivative of the values of the pen movement) exerted by the writer with a writing instrument during the writing of the sample.
