  • Method of classifying a finger touch in respect of finger pressure and fingerprint sensing system
    Patent number: 10782821
    Abstract: A method of classifying a finger touch in respect of a finger pressure on a surface of a fingerprint sensor, comprising the steps of: receiving, on the surface of the fingerprint sensor, a finger having a fingerprint topography; acquiring a first time-sequence of fingerprint images; determining a reference value of at least one image-related parameter indicative of a compression of the fingerprint topography, based on at least one fingerprint image in the first time-sequence of fingerprint images; acquiring a second time-sequence of fingerprint images; determining a test value of the at least one image-related parameter based on at least one fingerprint image in the second time-sequence of fingerprint images; and classifying the finger touch based on a relation between the test value and the reference value.
