Fingerprint image enhancement techniques using Gabor filters, including morphological segmentation, morphological thinning, windowed short-time Fourier transform enhancement, orientation map estimation and smoothing, and ridge frequency estimation and smoothing with MATLAB code implementation approaches
Recent studies on mathematical modeling of visual cortical cells [Kulikowski/Marcelja/Bishop:1982] propose a tuned band-pass filter bank structure, characterized by Gaussian transfer functions in the frequency domain. Implementation typically involves Gabor filter approximations through inverse Fourier transforms of Gaussian functions modulated by complex sinusoids.
Gabor 2D filter implementation for facial expression recognition - highly effective for face recognition applications. Includes filter bank generation, frequency domain implementation, and parameter optimization techniques.
Implementation of Gabor filter in MATLAB for texture feature extraction in digital image processing, including parameter configuration and practical application examples.
Gabor filters are widely used for shape detection and feature extraction applications, such as fingerprint image enhancement. This MATLAB implementation creates a 2D Gabor filter with adjustable frequency and orientation parameters. The core function gaborfilter1 processes input images through customizable frequency (f) and angle (theta) settings, producing multiple filtered outputs for comprehensive texture analysis.
