Resumen: A new technique for feature extraction based on a circular grid is proposed in this paper for off-line signature verification. Graphometric features for this new grid geometry are defined by adapting similar features available for rectangular grids. A Support Vector Machines (SVM) based classifier scheme is used for classification tasks and a comparison between the rectangular andthe circular grid approaches for feature extraction is performed. Experimental results show improvements in the verification performance with respect to the case of using rectangular grid based features, especially in the discrimination of simple and skilled forgeries. .
