Abstract
To realize the rapid and accurate signature verification, a new image processing method is developed on the basis of the optimal threshold algorithm. Firstly, the improved Gaussian filtering (IGF) algorithm is developed for the signature image to remove the noises. Secondly, the optimal threshold (OT) algorithm is developed to find the optimal threshold for the signature image segmentation. Finally, the deep learning method of a convolutional neural network is used to verify the signature image. It is experimentally proved that the IGF algorithm can get a better filtering effect, and the OT algorithm can obtain the better segmentation result, and the system has the better recognition accuracy.
