In this work we propose a method to quantify written signatures from digitalized images based on the use of
Elliptical Fourier Descriptors (EFD). As usually signatures are not represented as a closed contour, and
being that a necessary condition in order to apply EFD, we have developed a method that represents the
signatures by means of a set of closed contours. One of the advantages of this method is that it can
reconstruct the original shape from all the coefficients, or an approximated shape from a reduced set of them
finding the appropriate number of EFD coefficients required for preserving the important information in
each application. EFD provides accurate frequency information, thus the use of EFD opens many
possibilities. The method can be extended to represent other kind of shapes. |
