FPGA Implementation of Normalization block of Fingerprint Recognition Process

چکیده
The reliability of Fingerprint recognition process in turn the Fingerprint Recognition system depends on the minutiae. Accurate minutiae depend on the quality of the fingerprint image. Most of the images are of poor quality. This leads to distorted levels of variation in grey-level values along the ridges and valleys. These variations are minimized by adapting normalization process, which has pre-specified mean and variance. As well, normalization facilitates the subsequent Fingerprint recognition process. Implementation of normalization block of Fingerprint recognition process on Virtex-II Pro FPGA development board is proposed. As well, the comparison of FPGA results with Matlab is carried out.

FPGA Implementation of Orientation Field Estimation of Fingerprint Recognition Process
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 or...
