Abstract
A report is presented on a comparative study of three different
signal matching algorithms in the context of signature verification:
regional correlation, dynamic time warping, and skeletal tree matching.
The algorithm performances are compared in a single experimental
protocol over the same database. Algorithm performance is analyzed in
terms of verification error rates, execution time, and number and
sensitivity of algorithm parameters. Three different script types
(normal signatures, handwritten passwords, and initials) and three
different signal representation spaces (position, velocity, and
acceleration) are considered. Verification errors show that no algorithm
consistently outperforms the others in all circumstances
