FPGA Implementation of Orientation Field Estimation of Fingerprint Recognition Process
نویسنده
چکیده
Most of the automatic fingerprint verification systems are based on minutiae pattern matching. The accuracy of the system depends on the quality and location of minutiae. Most of the time, the quality of the ridges in the fingerprint image is not well defined. This leads to failure of precise location of minutiae. Hence, it is essential to get distinct ridges from the fingerprint images. The orientation field of a fingerprint image defines the local orientation of the ridges contained in the fingerprint. Distinct ridges provide accurate extraction of the minutiae from the fingerprint images. Implementation of orientation field estimation of fingerprint recognition process on Vertex-II Pro FPGA development board with verilog HDL is proposed.
