This dataset contains MATLAB code for frequency analysis of gravure printed finger patterns from the HYPA-p dataset. The developed algorithm performs 1-dimensional fast Fourier transform (FFT) on selected image data from the HYPA-p dataset, i.e. on all 'L-fields'. The peaks of the FFT-spectra correspond to the dominant distances of the fingers. Peak finding is performed after smoothing of the FFT-spectra with pre-defined filter kernels.
