A Circular Grid-Based Feature Extraction Approach for Off-line Signature Verification

In this paper, a new feature extraction approach based on a circular grid is proposed for off-line signature verification. Graphometric features used in the rectangular grid segmentation approach are adapted to this new grid geometry. A Support Vector Machine (SVM) based classifier scheme is used fo...
