In this work, an on-line signature verification system based on local information and on a one-class classifier, the Linear Programming Descriptor classifier (LPD), is presented. The information is extracted as time functions of various dynamic properties of the signatures, then the discrete 1-D wavelet transform (WT) is performed on these features. The Discrete Cosine Transform (DCT) is used to reduce the approximation coefficients vector obtained by WT to a feature vector of a given dimension… CONTINUE READING

Key Quantitative Results

  • We want to stress that our best fusion approach obtains an Equal Error Rate of 5.2% in the Skilled Forgeries, this value is the lowest Equal Error Rate reported in the literature for the SUBCORPUS-100 MCYT.
