FINGERPRINT VERIFICATION BASED ON IMAGE PROCESSING SEGMENTATION USING AN ONION ALGORITHM OF COMPUTATIONAL GEOMETRY

Abstract.

In this study, we applied a digital image processing system using the onion algo- rithm of Computational geometry to develop fingerprint verification. This method may be characterized as an alternative method to the used minutiae extraction algorithm proposed by Ratha et al. The proposed algorithm is also compared to a well-known commercial verification algorithm that is based on Ratha’s algorithm. In the experimental part the results of the above comparison showed that the proposed method yields correct positive and correct negative verification scores greater than 99%.
