SYSTEM AND METHOD FOR DISTORTION CONTROL IN LIVE-SCAN INKLESS FINGERPRINT IMAGES

摘要

In the disclosed computer systems and methods, the force and / or torque applied during the acquisition of an image of a biometric feature is determined to determine whether the pressure is very high or low or shear torque. If) is large, the image is rejected and the user / operator is notified to reacquire the image. Alternatively, the application of pressure and / or torque by the subject is mechanically limited so that the image is acquired only when the pressure and / or torque is within the acceptable range.
