In recent years, the number of students receiving football training in colleges has been increasing, however, during football trainings in most colleges and universities, high-intensity sports are generally performed. Therefore, the athletes often experience knee injury during training, which is harmful to the health of athletes and affects football players' professional skills improvement. This paper analyzes the reasons for the knee injuries of college football trainees, based on the artificial neural network technology and through the method of data analysis. This paper finds that football muscle damage types mainly include the medial collateral ligament, meniscus injury, anterior cruciate ligament, the knee bursitis, enthesopathy of the patellar tendon, and the lateral collateral ligament and Sinding Larsen and chondromalacia patellae these seven types.

With the construction of digital city and the rapid development of large-scale 3D data acquisition technology, 3D laser scanning and dense matching of aerospace images have produced massive point cloud data. As a new digital representation method of 3D objects, 3D point cloud has gradually become a common processing object in various research and engineering applications because of its simplicity and flexibility. 3D point cloud data can build a real 3D city model for 3D geographic information system, simulation and virtual technology, and digital city construction. How to use the existing computer processing ability to efficiently organize and index the massive point cloud data and complete the 3D spatial visualization modeling of the point cloud data more quickly and accurately has become an important research topic. Massive point cloud data are collected by 3D laser scanning system, and finally saved to the computer. Through some software processing, the high-precision 3D model is reconstructed, and the 3D reconstruction and rapid visualization of point cloud data are realized.

In order to improve the success rate and efficiency of automatic identification of low-voltage distribution topology, this paper proposes a record-based topology identification method. The topology recognition is divided into consumer-transformer relation recognition and hierarchical recognition. High-speed power line carrier (HPLC) automatic networking was used to obtain and judge the equipment information to generate the consumer-transformer relationship in the low voltage area. The topology terminal unit and low-voltage equipment with topology recognition function generate records through specific topology signal exchanging information. Then, the intelligent distribution transformer terminal unit summarizes these records and combines the relationship between power consumers and transformer to generate the hierarchical relationship. This topology identification method has the advantages of simple control logic, fast identification speed and high identification accuracy, which can provide the important basic data for real-time fault location, power line loss analysis and area capacity estimation and other advanced applications of low-voltage distribution.

Terahertz (THz) time-domain spectrum has been widely adopted as the de facto technique to inspect the physical characteristics of materials and to detect defects in bulks. However, the time series generated by scans are usually noisy and consist of minor peaks induced by the reflection of the defects inside the materials. To improve the quality of the data and to argument the frequency-domain spectrum of the signal, a Wiener filter modified by a time window is implemented to improve the dynamic range and the bandwidth of the frequency-domain spectrum. Software to make complex THz spectroscopy analysis and data visualization is developed, and the filters are expected to integrate into the numerical library of the software.

Object detection is an extremely important part of computer vision. However, the object detection result of R-FCN is not good enough in terms of speed and accuracy. In this paper, a novel architecture called Enhanced R-FCN (ER-FCN) is proposed for object detection. Two improvements are presented in ER-FCN. Firstly, novel anchor boxes, 3 scales with box areas of 5122, 2562 and 1282 pixels, and 3 aspect ratios of 0.618:1, 1:1 and 1:0.618, are designed to suit the different scales object detection in RPN. Hence, the performance of object localization and detection speed are increased. Secondly, since the softmax classifier is not optimal to deal with the binary classification problem, a Whale Optimization Algorithm based on support vector machine, termed WOA-SVM, is introduced to improve the accuracy of classification. Extensive experimental results on PASCAL VOC 2007 and PASCAL VOC 2012 datasets show that the mean average precision of ER-FCN is improved by 3.9% compared with that of R-FCN.
目标检测是计算机视觉的一个极其重要的组成部分。然而,R-FCN的目标检测结果在速度和精度上都不够好。本文提出了一种用于目标检测的增强R-FCN (Enhanced R-FCN, ER-FCN)结构。在ER-FCN中提出了两个改进。首先,针对RPN中不同尺度的目标检测,设计了新颖的锚盒,锚盒面积分别为5122、2562和1282像素,宽高比分别为0.618:1、1:1和1:0.618。从而提高了目标定位性能和检测速度。其次,针对softmax分类器在处理二值分类问题上的不优性,引入了一种基于支持向量机的Whale优化算法(WOA-SVM)来提高分类精度。在PASCAL VOC 2007和PASCAL VOC 2012数据集上的大量实验结果表明,与R-FCN相比,ER-FCN的平均精度提高了3.9%。

In order to solve the problem that the safety control effect of the traditional electrical equipment circuit system is relatively poor, combined with the big data analysis method, the automatic switch-off technology of the circuit switch of the electrical equipment is studied. According to the power control principle of the peaking unit, a PID algorithm is used to optimize the circuit safety control parameter algorithm. The active power generated by the pulse signal input into the coil drives the automatic control of the circuit switch in the electrical equipment, and accurately detects and controls the operation of the electrical equipment power system, thereby avoiding problems such as circuit failure. Finally, through experimental analysis, it is verified that the effect of the automatic switch-off of the circuit switch of the electrical equipment on the control of the circuit system has been significantly improved based on the analysis of big data, which is an important reference for the development of the electrical industry.

In order to meet the challenges of the new era to the research of digital oil painting, this paper puts forward the method of applying digital image processing technology to the research of digital oil painting. Through the digital image processing technology to analyze the large amount of information contained in the digital oil painting, combined with the new requirements of the new era for digital oil painting research, a set of digital oil painting research and development most suitable for the new era is formulated The new plan of the exhibition. Through long-term research and analysis, it is found that digital image processing technology has a profound impact on the research of digital oil painting. The research method proposed in this paper successfully provides a new idea for the research and development of digital oil painting.","PeriodicalId":373862,"journal":{"name":"2020 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114182355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the concept of “artificial intelligence” was first proposed in Dartmouth Conference in 1956, the discipline of artificial intelligence has entered an era of steady progress. Recently, the emergence of new technology such as big data, cloud computing and Internet of Things has promoted the rapid development of artificial intelligence technology represented by deep neural network.
自1956年达特茅斯会议首次提出“人工智能”概念以来,人工智能学科进入了一个稳步发展的时代。近年来,大数据、云计算、物联网等新技术的出现,推动了以深度神经网络为代表的人工智能技术的快速发展。
