Abstract
A fingerprint image processing device includes a memory, and a processor coupled to the memory. The processor performs operations. The operations include reading a tenprint card image which includes a plurality of fingerprint patterns and at least one ruled line to separate one fingerprint imprint area from another fingerprint imprint area, and extracting from the tenprint card image a fingerprint image which includes at least one of the fingerprint patterns, a part of a fingerprint imprint area, and a part of a next fingerprint imprint area
Claims3
A fingerprint image processing device comprising:
- a memory storing instructions;
- and
- at least one processor configured to execute the instructions to perform:
- storing a tenprint card image of a tenprint card, the tenprint card including rolled fingerprints of ten fingers and slap fingerprints of the ten fingers;
- segmenting a rolled fingerprint image and a slap fingerprint image from the tenprint card image;
- executing first matching the rolled fingerprint image of one hand and the slap fingerprint image of the other hand;
- outputting, in a case where a corresponding common region between the rolled print image of one hand and the slap print image of the other hand exists, a first warning message indicating that the corresponding common region is detected as a result of the first matching;
- in a case where a corresponding common region between the rolled fingerprint image of one hand and the slap fingerprint image of the other hand is not found, executing second matching the rolled fingerprint image of a one hand and the slap fingerprint image of the one hand;
- and
- outputting, in a case where a corresponding common region between the rolled fingerprint image of the one hand and the slap fingerprint image of the one hand is not found, a second warning message indicating that the fingerprint imprinting position of the rolled fingerprint or the slap fingerprint is found to be wrong as a result of the second matching.
