International Business Machines Corporation, Louis J F Chau & Associates Percello, May 16, 2000: US06064753 (47 worldwide citation)

A computer system and method determines the force and/or torque applied during the image acquisition stage of a biometric characteristic. Images with very high or very low pressure or high shear torque are rejected and user/operator is notified to re-acquire the image. Alternatively, the application ...
