MATLAB-Based Fingerprint Recognition System

Application Background: A texture analysis-based fingerprint recognition program developed using MATLAB. The program interface appears as follows: Input images must be 256x256 pixels, 8-bit grayscale, 500dpi fingerprints. If these specifications are not met, certain function parameters require modification. To execute the program in MATLAB, set the current directory as the working directory and type "fpextractdemo" in the command window. Key Technologies: Fingerprint image field computations (intensity field, gradient field, orientation field, frequency field), image segmentation, histogram equalization, image convergence, image smoothing, and image enhancement.
