Fingerprints are the marks left by the friction of human fingers. Fingerprint identification compares two friction skin impressions of human fingers or toes to resolve whether the impressions may have come from the same person. Fingerprint identification is one of the biometric identification technologies. Most mainstream fingerprint identification algorithms are based on artificially predefined traditional fingerprint features, such as orientation field and singular point. However, because these algorithms rely heavily on artificial predefined features, when the image noise is large, the artificial predefined features cannot be extracted effectively, resulting in poor identification accuracy. After 2012, some researchers used convolutional neural networks for fingerprint identification tasks and achieved higher accuracy. However, this paper believes that the fingerprint images have relatively special curves, so the traditional convolutional neural network algorithms cannot fully extract the characteristics of the curves. Therefore, this paper proposes the siamese rectangular convolutional neural networks (SRCNN) algorithm to solve this problem. This paper presents the detailed architecture of SRCNN and experiments on NIST Special Database 4. The experimental results show that the accuracy of SRCNN is 4% higher than that of traditional convolutional neural networks on the test set. That is to say, SRCNN performs better than traditional convolutional neural networks in fingerprint recognition tasks.

Industrial Automation (IA) and Artificial Intelligence (AI) need an integrated platform. Due to the uncertainty of the time required for training or reasoning tasks, it is difficult to ensure the real-time performance of AI in the factory. Thus in this paper, we carry out a detailed survey on cloud-edge computing-based Industrial Cyber Intelligent Control Operating System (ICICOS) for industrial automation and artificial intelligence. The ICICOS is built based on IEC61499 programming method and used to replace the obsolete Programmable Logic Controller (PLC). It is widely known that the third industrial revolution produced an important device: PLC. But the finite capability of PLC just only adapts automation which will not be able to support AI, especially deep learning algorithms. Edge computing promotes the expansion of distributed architecture to the Internet of Things (IoT), but little effect has been achieved in the territory of PLC. Therefore, ICICOS focuses on virtualization for IA and AI, so we introduce our ICICOS in this paper, and give the specific details.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
