Effective Implementation techniques in Offline Signature Verification
M. Madhavi · IOSR Journal of Computer Engineering · 2012
Handwritten signature verification has long been in use for human identity verification in banks, offices etc.There are both online signature verification techniques as well as offline signature verification techniques.Each technique has its own advantages and disadvantages.This paper compares the results of implementation of three simple offline signature verification techniques.These three filtering techniques are simple mask filtering technique, Local binary pattern and Local Directional pattern.In all these techniques, the original image will be converted to a grayscale image by eliminating the hue and saturation information while retaining the luminance.Next score values will be calculated using each of these techniques.A simple local database of various kinds of signatures is used.A comparison is made based on the scores to evaluate the accuracy of each of these techniques.
