Paper Abstract

In crime detection and security verification, fingerprint identification is extremely important. However, in the real- world fingerprint images are not distortion free. In the present work, a distortion-invariant identification method for fingerprint images is developed. The sources of distortion of fingerprint data that are considered are rotation, scaling and erosion. It is shown that rotated fingerprint images with 95% of missing data can still be recognized.
