The rapid advancement of artificial intelligence(AI) has significantly impacted photonics, creating a symbiotic relationship that accelerates the development and applications of both fields. From the perspective of AI aiding photonics, deep-learning methods and various intelligent algorithms have been developed for designing complex photonic structures, where traditional design approaches fall short. AI's capability to process and analyze large data sets has enabled the discovery of novel materials, such as for photovoltaics,leading to enhanced light absorption and efficiency. AI is also significantly transforming the field of optical imaging with improved performance. In addition, AI-driven techniques have revolutionized optical communication systems by optimizing signal processing and enhancing the bandwidth and reliability of data transmission. Conversely, the contribution of photonics to AI is equally profound. Photonic technologies offer unparalleled advantages in the development of AI hardware, providing solutions to overcome the bottlenecks of electronic systems. The implementation of photonic neural networks, leveraging the high speed and parallelism of optical computing, demonstrates significant improvements in the processing speed and energy efficiency of AI computations. Furthermore, advancements in optical sensors and imaging technologies not only enrich AI applications with high-quality data but also expand the capabilities of AI in fields such as autonomous vehicles and medical imaging. We provide comprehensive knowledge and a detailed analysis of the current state of the art, addressing both challenges and opportunities at the intersection of AI and photonics. The multifaceted interactions between AI and photonics will be explored, illustrating how AI has become an indispensable tool in the development of photonics and how photonics, in turn,facilitates advancements in AI. Through a collection of case studies and examples, we underscore the potential

Wide-Area Overlays of Virtual Workstations (WOWs) have been shown to provide excellent infrastructure for deploying high throughput computing environments on commodity desktop machines by (I) offering scalability to a large number of nodes, (2) facilitating addition of new nodes even if they are behind NATs/Firewalls and (3) supporting unmodified applications and middleware. However, deployment of WOWs from scratch still requires setting up a bootstrapping network and managing centralized DHCP servers for IP address management. In this paper we describe novel techniques that allow multiple users to create independent, isolated virtual IP namespaces for their WOWs without requiring a dedicated bootstrapping infrastructure, and to provision dynamic host configuration (e.g. IP addresses) to unmodified DHCP clients without requiring the setup and management of a central DHCP server. We give qualitative and quantitative arguments to establish the feasibility of our approach, © 2007 IEEE.

Connectivity constraints due to Internet route outages and symmetric NATs create situations when direct communication is not possible between nodes in P2P deployments, often leading to high latency between high-traffic nodes. In such cases, it is possible to reduce end-to-end latency by routing their communication through another node in the P2P system that is selected based on its Internet latencies to end-nodes. In this paper, we present and compare two decentralized algorithms for discovering low-latency proxy nodes between high-traffic nodes: (1) selecting a node with least Internet latency from the set of randomly-chosen neighbors to which one of the end-nodes is directly connected, and (2) discovery using latency estimates based on network coordinates. We evaluate these techniques in context of IP-over-P2P virtual networks through experiments on realistic wide-area testbeds. Our results indicate that in a network with over 400 nodes on PlanetLab, both the techniques select proxies such that the median penalties over the global optimal are within 16% and 21%, respectively, when all nodes are able to serve as proxies. We also investigate scenarios where subsets of nodes have connectivity constraints preventing them from serving as proxies.© 2010 IEEE.

Self-configuring virtual networks rely on structured P2P routing to provide seamless connectivity among nodes through overlay routing of virtual IP packets, support decentralized hole-punching to establish bi-directional communication links among nodes behind network address translators, and dynamic configuration of virtual IP addresses. Our experiences with deployments of virtual networks in support of wide-area overlays of virtual workstations (WOWs) reveal that connectivity constraints imposed by symmetric NATs and by Internet route outages often hinder P2P overlay structure maintenance and routability, subsequently limiting the ability of WOWs to deliver high-throughput computing through aggregation of resources in different domains. In this paper, we describe and evaluate two novel approaches which are generally applicable and fully decentralized, and show that they improve routability of structured P2P networks in such connectivity constrained environments: (1) a fault-tolerant routing algorithm based on simulated annealing from optimization theory, and (2) tunneling of connections between adjacent nodes (in the P2P identifier space) over common neighbors when direct communication is not possible. Simulation-based analyses show that when pairs of nodes only have 70% chance of being able to communicate directly, the described approaches improve all-to-all routability of the network horn 90% to 99%. We have implemented these techniques in the IP-over-P2P (IPOP) virtual network and have conducted experiments with a 80-node WOW Condor pool, demonstrating that, at 81% probability of establishing a pair-wise connection, annealing and tunneling combined allow all nodes to be connected to the pool, compared to only 160 nodes in the absence of these techniques.

In this paper, we propose a spatial temporal video-text detection technique which proceed in two principal steps: potential text region detection and a filtering process. In the first step we divide dynamically each pair of consecutive video frames into sub block in order to detect change. A significant difference between homologous blocks implies the appearance of an important object which may be a text region. The temporal redundancy is then used to filter these regions and forms an effective text region. The experimentation driven on a variety of video sequences shows the effectiveness of our approach by obtaining a 89,39% as precision rate and 90,19 as recall.

Today's mobile devices or smartphones have a revolutionary impact on how we communicate, especially after the advent of devices like smart watches and Google glasses that require new ways to interact with them. To optimise the use of mobile devices, special input and output peripherals have been designed over the years to facilitate communication with them. The well known peripherals are the multi-touch screens. Smartphones are too small to work freely using their input screens. To solve this problem, recent research has focused on contactless and natural gestural interfaces. In this context, we propose a hand gesture recognition system for mobile devices as a simple way of communication with smartphones. In this work, we describe a hand gesture recognition system for Android devices based on a combination of HOG and LBP features and the SVM classifier. An accuracy rate of about 95% is obtained on the improved 'NUS database I'. In addition, we conduct experiments on different Android devices to know the impact of using such a recognition task on embedded systems like smartphones. © 2020 Inderscience Enterprises Ltd.

3D Ear Shape Matching Using Joint -Entropy

In this article, we investigate the use of joint a-entropy for 3D ear matching by incorporating the local shape feature of 3D ears into the joint a-entropy. First, we extract a sut^cient number of key points from the 3D ear point cloud, and fit the neighborhood of each key point to a single-value quadric surface on product parameter regions. Second, we define the local shape feature vector of each key point as the sampling depth set on the parametric node of the quadric surface. Third, for every pair of gallery ear and probe ear, we construct the minimum spanning tree （MST） on their matched key points. Finally, we minimize the total edge weight of MST to estimate its joint a-entropy the smaller the entropy is, the more similar the ear pair is. We present several examples to demonstrate the advantages of our algorithm, including low time complexity, high recognition rate, and high robustness. To the best of our knowledge, it is the first time that, in computer graphics, the classical information theory of joint a-entropy is used to deal with 3D ear shape recognition.

Metamaterial absorbers realized in an X-band rectangular waveguide

引用

Chinese Physics B 2012年第11期21卷 474-478页

作者：黄勇军文光俊李建钟靖平王平孙元华 O.Gordon 朱卫仁 Key Laboratory of Broadband Optical Fiber Transmission&Communication Networks School of Communication and Information EngineeringUniversity of Electronic Science and Technology of China Advanced Computing and Simulation Laboratory(AχL) Department of Electrical and Computer Systems EngineeringMonash University

In this paper, we demonstrate six types of metamaterial absorbers （MMAs） by measuring their absorptivities in an X-band （8 12 GHz） rectangular waveguide. Some of the MMAs have been demonstrated previously by using the free space measurement method, and the others are proposed firstly in this paper. The measured results show that all of the six MMAs exhibit high absorptivities above 98%, which have similar absorbing characteristics to those measured in the free space. The numerically obtained surface current densities for each MMA show that the absorbing mechanism is the same as that under the free space conditions. Such a demonstration method is superior to the conventional free space measurement method due to the small-scale test samples required, the simple measure device, and its low cost. Most importantly, the proposed method opens a way to enable MMAs to be used in microwave applications such as matched terminations.
