Research on UAV Target Detection Algorithm Based on Improved Air-Borne-YOLOv3 基于改进机载- yolov3的无人机目标检测算法研究
Hao Wang, Huajun Gong, Yourong Fan, Xinhua Wang
While the rapid development of multi-rotor UAVs brings wide applications, it also brings harm to social life and personal safety due to problems such as “indiscriminate flying” and “black flying”. Therefore, there is an urgent need to carry out research work on anti-VAV systems. The most critical technology in the countermeasure system is the real-time detection of the target UAV. The traditional YOLOv3 detection algorithm cannot achieve a balance between real-time performance and detection accuracy on airborne embedded devices with limited computing power. Therefore, this paper first improves the end structure of MobileNetV3-Small and replaces the backbone network of the original YOLOv3 with it, which greatly reduces the amount of calculation, but brings about the loss of detection accuracy; Next, an improved receptive field module(RFB+) is added, which strengthens the detection ability of targets in complex backgrounds; Finally, the improved YOLOv3 algorithm is named Air-Borne-YOLOv3. The feasibility and superiority of the improved algorithm are proved by the actual flight test results.
多旋翼无人机在快速发展带来广泛应用的同时,也因“乱飞”、“黑飞”等问题给社会生活和人身安全带来危害。因此,迫切需要开展抗变风量系统的研究工作。对抗系统中最关键的技术是对目标无人机的实时检测。传统的YOLOv3检测算法无法在计算能力有限的机载嵌入式设备上实现实时性和检测精度的平衡。因此,本文首先对MobileNetV3-Small的端部结构进行了改进,用原来的YOLOv3骨干网代替了原来的YOLOv3,这样大大减少了计算量,但带来了检测精度的损失;其次,加入改进的感受野模块(RFB+),增强了复杂背景下的目标检测能力;最后,将改进后的YOLOv3算法命名为Air-Borne-YOLOv3。实际飞行试验结果证明了改进算法的可行性和优越性。

A Novel Approach for Image Dehazing via Spatial and Channel Feature Fusion 一种基于空间和通道特征融合的图像去雾方法
Duofeng Wang, Yanbo Zhang, Zilun Wan, Fengyang Gu, Mingyue Chen, Yurong Zhou, Yong Zhang, Yi Zhu
The quality of images collected outdoors is compromised owing to hazy weather, resulting in contrast reduction and degradation. To solve this problem, a new dehazing algorithm that combines spatial and channel feature maps was proposed. The algorithm comprises of two parts: image dehazing and image enhancement. The first part uses the anti-symmetric nature of the Involution operator and the convolution operator to extract the spatial and channel feature maps of the hazy image completely. This part can restore the dehazed image by combining it with a deformed atmospheric scattering model. In the second part, a contrast-limited adaptive histogram equalization algorithm is used to improve the dehazed image. This process can improve the contrast and brightness of an image and enhance its detailed information. The experiment used the structural similarity index measure(SSIM), peak signal-to-noise ratio(PSNR), and other parameters to compare the algorithm with three other common dehazing algorithms to verify the dehazing effect and robustness of the algorithm. The experimental results show that the proposed algorithm improved the SSIM and PSNR by 4.72% and 15.96% respectively.
由于雾霾天气,室外采集的图像质量受到影响,导致对比度降低和退化。为了解决这一问题,提出了一种结合空间和通道特征映射的去雾算法。该算法包括图像去雾和图像增强两部分。第一部分利用对合算子和卷积算子的反对称性质,完整地提取了模糊图像的空间和通道特征映射。该部分通过与变形的大气散射模型相结合来恢复去雾图像。第二部分采用对比度有限的自适应直方图均衡化算法对去雾图像进行改进。这个过程可以提高图像的对比度和亮度,增强图像的细节信息。实验采用结构相似度指标(SSIM)、峰值信噪比(PSNR)等参数,将算法与其他三种常用的除雾算法进行比较,验证算法的除雾效果和鲁棒性。实验结果表明,该算法将SSIM和PSNR分别提高了4.72%和15.96%。

A Lightweight Countermeasure of SM4 against Side Channel Analysis 一种针对侧信道分析的SM4轻量化对策
Weijun Shan, Chi Zhang, Qing Li, Jun Yu
This paper presents a lightweight countermeasure scheme of SM4 cryptographic algorithm against side channel analysis attacks. SM4 is one of the widely used block ciphers in information computing and data communication. However, as it is usually implemented in cryptographic devices, it is definitely under the threat of side channel analysis attacks. Some schemes of implementations have been provided as the countermeasures against the side channel analysis attacks, which leads to a relatively complicated realization on both cost and performance. This paper proposes a new mask scheme for SM4 implementation with lightweight cost and low performance loss. Experiment results show the effectiveness of the method against the side channel analysis attacks.
提出了一种轻量级的SM4密码算法对抗侧信道分析攻击的对策方案。SM4是一种广泛应用于信息计算和数据通信的分组密码。然而,由于它通常是在加密设备中实现的,因此它肯定会受到侧信道分析攻击的威胁。针对侧信道分析攻击,已经提出了一些实现方案,但在成本和性能上都比较复杂。本文提出了一种低成本、低性能损失的SM4掩码实现方案。实验结果表明了该方法对侧信道分析攻击的有效性。

Research on the Impact of China's Economic Cooperation with the “Belt and Road” Countries from a Cross-Cultural Perspective 跨文化视角下中国与“一带一路”国家经济合作的影响研究
Sixiao Zou
With the gradual deepening of economic globalization, the frequency of cross-cultural business cooperation between countries has gradually increased. Whether at the macro or micro level, communication obstacles and economic losses caused by different cultural backgrounds to the economic exchanges of countries are also increasing. This paper selects the economic cooperation data (2014–2021) of 29 countries along the “Belt and Road” that have economic relations with China, uses Hofstede's cultural index to calculate the cultural distance between China and these countries along the route, and uses the extended gravity model to conduct empirical tests, The result shows that cultural distance does have an impact on bilateral economic cooperation, and there are differences due to regional differences.

Zhixiao Wang, Wenyao Yan, Zhuochun Li, Min Huang, Qinyuan Fan, Xin Wang
Domestic violence (DV) is getting more and more attention due to the critical trouble and danger that pose great challenge to human rights and health. The popularity of various social medias can help these victims to share their experiences and obtain more possible support from numerous open communities. However, it is not only inefficient but also laborious and time-consuming to manually access and browse through a great deal of available posts on the Internet and social media space. Therefore, considering the advantages of Deep Learning (DL) technology in Natural Language Processing, adopting DL as an efficient strategy for automatic recognition and evaluation of DV victims is in the urgent requirements. This paper takes social media Facebook posts about domestic violence as the research object and uses Word2Vec to build word vector model. The paper uses Bi-LSTM+self-Attention deep learning models to accomplish DV crisis recognition task and compares it with CNN, RNN and LSTM. The assessment of experimental results show that the accuracy of CNN and LSTM are both above 90% which is better than RNN; And the accuracy of Bi-LSTM is the highest after using the Attention mechanism. The research results of this article will provide reference and help for public DVCS to rescue DV victims.
由于家庭暴力给人权和健康带来了巨大的挑战和危害,越来越受到人们的关注。各种社交媒体的普及可以帮助这些受害者分享他们的经历,并从众多开放社区获得更多可能的支持。然而,手动访问和浏览互联网和社交媒体空间上的大量可用帖子不仅效率低下,而且费力且耗时。因此,考虑到深度学习技术在自然语言处理中的优势,采用深度学习作为一种有效的策略对家庭暴力受害者进行自动识别和评估是迫切需要的。本文以社交媒体Facebook上有关家庭暴力的帖子为研究对象,使用Word2Vec构建词向量模型。本文采用Bi-LSTM+自注意深度学习模型完成DV危机识别任务,并与CNN、RNN和LSTM进行比较。实验结果评估表明,CNN和LSTM的准确率均在90%以上,优于RNN;使用注意机制后,Bi-LSTM的准确率最高。本文的研究成果将为公共DVCS救助家庭暴力受害者提供参考和帮助。

Recognition of Human-object Interaction in Video through a Two-stream Network Integrating Multiple Features 基于多特征融合的两流网络视频中人-物交互识别
Lunzheng Tan, Rui Ding
To understand a scene, a machine not only has to learn to recognize individual object instances, but also pair them up and recognize visual relationships between them. Human-object interaction (HOI) recognition is one of the fundamental tasks in understanding the visual world. In this paper, we address the task of understanding and recognizing HOI in videos, and represent HOI as the doublet of . This paper proposes a two-stream network model that fuses multiple features. Since appearance information (the appearance features of instances), spatial information (the distance between each key part of the human body and the interacting object), and motion information (optical flow) in the video are all essential cues for recognizing HOI, our model uses two streams to fuse the information to complete the HOI recognition task. We valid the effectiveness of the model by conducting experiments on two recently proposed public video datasets (Charades and CAD-120 datasets), and perform ablation experiments to show the effect of components.
为了理解一个场景,机器不仅要学会识别单个对象实例,还要将它们配对并识别它们之间的视觉关系。人机交互(HOI)识别是理解视觉世界的基本任务之一。在本文中,我们解决了理解和识别视频中HOI的任务,并将HOI表示为。本文提出了一种融合多特征的双流网络模型。由于视频中的外观信息(实例的外观特征)、空间信息(人体各关键部位与交互对象之间的距离)和运动信息(光流)都是识别HOI的重要线索,因此我们的模型使用两个流来融合信息以完成HOI识别任务。我们通过在最近提出的两个公共视频数据集(Charades和CAD-120数据集)上进行实验来验证该模型的有效性,并进行烧蚀实验来显示组件的影响。

Time-consuming, labor-intensive, poor real-time performance, and similar problems of artificial station inspection need to be solved. Here, an AR inspection system is proposed to replace manual inspection to effectively monitor the working status of equipment and improve the design method of intelligent inspection systems, which are used to monitor onsite environmental conditions. This proposed method uses a panoramic camera to capture onsite audio and video data, collects a variety of sensor data, and integrates these two types of data in real time. The method can provide intelligent anomaly detection and alarm functions and push audio and video streams to the office terminal through RTMP protocol, indicating great convenience for patrol inspection.
