Wavelet‐Markov local descriptor for detecting fake fingerprints
Diego Gragnaniello, Giovanni Poggi, Carlo Sansone, Luisa Verdoliva · Electronics Letters · 2014
The use of a wavelet‐Markov local descriptor, which exploits joint dependencies among wavelet coefficients, for fingerprint liveness detection, is proposed. On the LivDet 2009 datasets, a properly trained support vector machine classifier based on this descriptor guarantees an average error below 3%, as opposed to the 8% average error of the best conventional techniques.
