On feature extraction using gabor filter and feature relation graph for offline signature verification
The most important and difficult stage of each offline signature verification system is feature extraction stage. The performance of the system mainly depends on effectiveness of the feature extraction algorithm. Current methods in this domain make use of different feature extraction and classificat...
