Class Information
Number: 382/120
Name: Image analysis > Applications > Personnel identification (e.g., biometrics) > Using a signature > Sensing pressure together with speed or acceleration
Description: Subject matter wherein the pressure characteristics of the writing sample are used in combination with either 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) characteristic to identify the person doing the writing.
