Invariant features comparison in hidden markov model and SIFT for offline handwritten signature database
Mr.Neeraj Shukla, Madhu Shandilya · International Journal of Computer Applications · 2010
In Handwritten signatures analyzed for forgery have to undergo feature extraction process, due to varied samples in size rotation and intra-domain changes, invariance has to be achieved during feature extraction process; circular Hidden Markov Model with discrete radon transform approach of feature extraction provides invariance.On other hand Scale Invariant Feature Transform
