FPEXTRACTDEMO Fingerprint Feature Extraction Demonstration Program

The FPEXTRACTDEMO Fingerprint Feature Extraction Demonstration Program serves as a practical fingerprint processing tool implementing multiple standard algorithms for streamlined feature extraction. The program provides the following configurable options with corresponding technical implementations: - Centralize: Performs image binarization using thresholding algorithms and calculates the centroid coordinates through moment calculations - Crop: Executes image trimming operations to remove extraneous regions using bounding box detection - Sectorize: Implements radial sector visualization for intuitive pattern analysis through polar coordinate transformation - Normalize: Applies intensity normalization to ensure data consistency using statistical scaling methods - Gabor filters: Visualizes Gabor filter banks demonstrating orientation-selective frequency filtering for ridge enhancement - Convolute: Computes convolution operations between input images and Gabor filters using 2D spatial filtering techniques - Features: Generates visual representations of fingerprint minutiae patterns including ridge endings and bifurcations - FingerCode: Implements database integration functionality for storing fingerprint templates using feature vector encoding - Check: Performs fingerprint matching through template comparison algorithms using distance metric calculations This comprehensive toolset enables effective utilization of the FPEXTRACTDEMO program for fingerprint analysis and verification tasks.
