The aim of our work is to realize the implementation of a real-time image rotation on FPGA's board. The method we used is based on a B-spline interpolator. The integration capicity of FPGAs is relatively weak, so the difficulty in this problem is to determine the right coding of the rotation filter while keeping a good accuracy on filtering output. In this article, we remind a few definitions about...
In fingerprint recognition system, fingerprint feature extraction algorithm requires good quality fingerprint images to produce good results. Therefore, one step in the preprocessing stage is image enhancement to improve the quality of poor fingerprint image, so the minutiae points can be detected with good results. In this paper, we present how this enhancement process in simple minutiae detection...
