Fingerprint Sensing and Enrollment

摘要

A sequence of biometric data images is received, such as, for example, a sequence of fingerprint images, and a set of biometric data images is selected from the sequence of images. The set of images can include one or more segments of at least one image in the sequence of images. One or more portions of at least one image of biometric data in the set of images can be selected to be included in the unified image of biometric data. The unified image of biometric data can be constructed using the one or more portions of the at least one image of biometric data. If the unified image of biometric data is not complete, a user can be prompted for one or more additional images of biometric data.

主权项

1. A method for constructing a unified biometric image, the method comprising:
receiving a sequence of images of biometric data from a biometric recognition sensor; as the images of biometric data in the sequence are received, repeatedly selecting a sliding window of images of biometric data from the sequence, wherein:
each sliding window comprises a subset of the images of biometric data in the sequence, anda number of images of biometric data in each subset comprises:
at least two of the images of biometric data in the sequence but less than a total number of the images of biometric data in the sequence, andat least one image of biometric data that is not included in a preceding sliding window; selecting one or more images of biometric data from the subset of images of biometric data in at least one sliding window; and including the selected one or more images of biometric data in the unified biometric image.
