An Efficient Offline Signature Verification System

M. Arathi, A. Govardhan
2014 International Journal of Machine Learning and Computing  
Offline signature verification is one of most challenging area of pattern recognition. Many methods have been introduced in literature to find whether a given signature is genuine or forgery.  ...  In the proposed work, the signature image is converted into time series data using linear scanning method and then time series shapelets are identified to distinguish genuine signatures from forged ones  ...  But requirement of acquiring the signature on some special arrangement makes the online method unsuitable for many of the practical uses.  ...

Biometric signature verification system based on freeman chain code and k-nearest neighbor

Aini Najwa Azmi, Dewi Nasien, Fakhrul Syakirin Omar
2016 Multimedia tools and applications  
In the first part of feature extraction stage, the FCC was extracted by using boundary-based style on the largest contiguous part of the signature images.  ...  A Signature Verification System (SVS) is a solution for such situation. The system can be decomposed into three stages: data acquisition and preprocessing, feature extraction and verification.  ...  On the other hand, images in an online system contains less or zero noise, so less effort is needed for the pre-processing of the online system.  ...
