Abstract

Offline signature verification is a difficult task in the biometric authentication domain, with particular importance in legal documents, banking activities, and identity management systems. The performance of offline signature verification systems is heavily reliant on the quality of features extracted. Feature extraction forms the cornerstone upon which sophisticated models perceive, analyze, and make sense of digital data. This paper delves into the intricacies of feature extraction, examining its significance and associated challenges. In this paper, three feature extraction methods, namely Histogram of Oriented Gradients (HOG), which captures directional and structural local edges, GLCM (capturing statistical texture information), and Local Binary Pattern (LBP), have been exploited. Instead of using a single classifier, a Voting Classifier is used, which includes Support Vector Machines (SVM), Random Forests (RF), and K-nearest neighbor (KNN) for discriminating genuine and forged signatures. The proposed models are evaluated on five benchmark datasets: CEDAR, BHSig260 (Bengali and Hindi), UTSig, and MCYT-75.
