摘要： A method for enrolling biometric images including the steps of: a) capturing (310) a plurality of images for a user into a capture folder; b) selecting (318) one of the plurality of images in the capture folder and removing the selected image from the capture folder to an enroll folder; c) comparing (322) the selected image to each of the remaining images in the capture folder to generate a corresponding similarity score for each of the remaining images; d) determining (326) whether any of the corresponding similarity scores are at least equal to a predetermined score threshold, and removing each image having a corresponding similarity score at least equal to the predetermined score threshold from the capture folder to a delete folder (330); and e) determining (334) whether there is at least one image in the capture folder and if so repeating steps b) through d).

摘要： A method is performed in a print identification system to segment a non-segmented slap print image into its finger components. The method includes: receiving, for a hand, a non-segmented slap print image and a corresponding plurality of roll print images each corresponding to a different finger number; comparing the roll print images to the non-segmented slap print image to determine a number of mated minutiae areas on the non-segmented slap print image; detecting a number of print components from the non-segmented slap print image using the plurality of mated minutiae areas; and selecting a number of final print components from the detected print components and assigning finger numbers to the final print components, using the plurality of mated minutiae areas.

摘要： A method for fingerprint record identification includes the steps of: assigning (200) a first number of fingers for a first matching stage and a second number of fingers for a second matching stage; performing (210) the first matching stage of comparing, based on the first number of assigned fingers, a search record to at least a portion of a plurality of file records and generating first matching results of a subset of the at least a portion of the plurality of file records; and performing (220) the second matching stage of comparing, based on the second number of assigned fingers, the search record to at least a portion of the subset and generating second matching results of one of: a strong hit; a weak hit; no hit; and a an ordered portion of the subset.

摘要： A method for comparing a first print image having a first set of minutiae to a second print image having a second set of minutiae, wherein at least a second subset of minutiae from the second set is mated to a first subset of minutiae from the first set, the method that includes the steps of: selecting (350) a first pair of minutiae from the first subset and a second pair of corresponding mated minutiae from the second subset; generating (350) a first segment based on the first pair of minutiae and a second segment based on the second pair of minutiae; generating (360) a first cross-section profile based on the first segment and a second cross-section profile based on the second segment; and computing (365) at least one similarity measure that is indicative of the similarity between the first cross-section profile and the second cross-section profile.

摘要： A method for use in print matching apparatus that includes the steps of: enrolling (200) a print of a user; extracting (210) a set of matching features from the enrolled print; comparing (220) the extracted features of the enrolled print to extracted features of each print in a set of reference prints, wherein each reference print in the set is from a person other than the user, and determining a highest non-matching score; determining (230) at least two minimum and maximum threshold pairs based on characteristics of the print matching apparatus; and storing (240) the matching features of the enrolled print, the highest non-matching score, and the at least two maximum and minimum threshold pairs for use in verifying a subsequently captured print of the user.
