Signature alignment based on GMM for on-line signature verification
作者:
Highlights:
• Signatures are aligned well to reference template based on Gaussian Mixture Model before verification.
• Efficiency of verification is improved by modified dynamic time warping with signature curve constraint.
• Distance probability is presented to describe the dissimilarity between test signatures and references.
• A strategy of dynamic weight factors being assigned to features depend on coefficient of variation.
