But, existing feature point extraction mode as described above classification or identification as fingerprint due to following limitation
Limitation so that the reason for break down.
- the first, it is not easy the characteristic point for the fingerprint that setting is received by camera or line scanning device with being deposited for certification
The benchmark point of the characteristic point of the fingerprint of storage.The fingerprint inputted by camera or line scanning device is manually operated come real
Existing, therefore, the center of image is inconsistent.Also, the characteristic of the skin histology due to composition fingerprint, in each input, part
Characteristic point may be reappeared or is not transfused to.Therefore, the characteristic point of extraction can not be with the fingerprint registered for certification
Characteristic point is completely the same.
- the second, it is difficult to which rapid extraction is located at the position of the core point (core) at the center of fingerprint.For judging characteristic point
Consistent degree, can extract and using fingerprint central point, still, need by multiple crestal lines come the gradient that converts, therefore, increase for this
