Essay: Rules where the Science of Fingerprints is based on

Sample Essay

1) They are “permanent” in that they are formed in the fetal stage, prior to birth, and remain the same throughout lifetime, barring disfiguration by scarring, until sometime after death when decomposition sets in. That means that the prints do not change during a life time. That’s not all true because fingerprints do change, but the changes can be explained. If not, they can’t be identified. The changes can be made by: flexibility from the skin, growing, a dirty finger, scarring, a wound, or a disease of the skin.

Essay: Fingerprint Imaging

Sample Essay

Fingerprint imaging technology is the process of electronically capturing and enhancing the unique pattern of ridges and minutiae within a fingerprint image. The fingerprint image is captured by using an optical, pressure, or capacitive scanner. An optical scanner captures the fingerprint image by using light to illuminate the fingerprint ridges placed on a glass surface and records the reflection of this light. In order to ensure that the performance of the system will be robust, with respect to the quality of the fingerprint images, it is essential to incorporate a fingerprint enhancement algorithm to filter out image noise and reliably extract ridge and minutiae from the fingerprint image.
