Offline Signature Verification using Local Binary Pattern
Keywords:
Biometrics, Local binary pattern, offline signature verification, histogram, chi-square distance.Abstract
Several papers have appeared in literatures which propose features for offline signature verification. In this paper local binary pattern of signature is used as one of the feature for verification purpose. The histograms of original signature and forgery signature are calculated and chi-square distance of them is used as input to the classifier. Before classification signature image goes throw several steps as pre-processing, feature extraction and classification. Pre-processing includes thresholding, skeletonization and binarization in this paper Otsu thresholding is used and skeletonization of the thresholded image is used for feature calculation. The local binary pattern (LBP) of an image is calculated then histogram of the LBP.
