Abstract
In a method for generating an estimated fingerprint image, a ridge/valley pattern of a fingerprint of a finger is received. A sensor image including a partial fingerprint of the finger is received. Ridge/valley characteristics of the fingerprint are extracted from the sensor image including the partial fingerprint. An estimated fingerprint image is generated based at least on the ridge/valley pattern of the fingerprint and the ridge/valley characteristics of the fingerprint.
