TL;DR: In this article, the authors used a pretrained deep convolutional neural network (DCNN) model for feature extraction using transfer learning and further used neighborhood component analysis to reduce the irrelevant features.
Abstract: Advance trends adopted in classification of images using deep learning networks have paved opportunities for handwritten signature identification and verification. Convolution neural network has demonstrated to be profoundly proficient in image classification, yet this methodology has a few weaknesses also. Notably, a huge number of images are required for training to achieve high level of a precision for classification. Transfer learning with pretrained deep convolution neural network model can be utilized to conquer these issues. To bring about further enhancements in terms of recognition rate, storage and computational time, feature selection procedure plays a key role by distinguishing the most significant features. In this work, we used a pretrained DCNN model, i.e., GoogLeNet for feature extraction using transfer learning and further used neighborhood component analysis to reduce the irrelevant features. Support vector machine is used for classification. Experiments have been conducted using three signature datasets, i.e., CEDAR, SigComp2011 and UTSig.

TL;DR: Research has shown a high efficiency of verification using proposed method, and the similarity between signatures is assessed by determining the similarity of vectors in the compared signatures.
Abstract: In this paper a new method of handwritten signatures verification has been proposed. This method, for each signature, creates complex features which are describing this signature. These features are based on dependencies analysis between dynamic features registered by tablets. These complex features are then used to create vectors describing the signature. Elements of these vectors are calculated using measures proposed in this work. The similarity between signatures is assessed by determining the similarity of vectors in the compared signatures. Research, whose results will be presented in the further part of this work, have shown a high efficiency of verification using proposed method.

TL;DR: The experimental results show that image recognition accuracy of the proposed OWSVM method is better than that of OWBPNN.
Abstract: Image recognition belongs to the nonlinear classification problem, which has a certain difficulty in the process of image recognition. Image recognition based on optical wavelet and support vector machine is proposed in the paper. Optical wavelet is used to extract the features of images and support vector machine is used to create the image recognition model by utilizing the features. In the experiments, 80 images with 9 classes are used to study the effectiveness of the proposed OWSVM method. Image recognition accuracy of the proposed OWSVM method is 96.25 and image recognition accuracy of OWBPNN is 88.75.The experimental results show that image recognition accuracy of the proposed OWSVM method is better than that of OWBPNN.
