摘要: The life cycle of a smartphone is decreasing rapidly, which leads to a lot of electronic waste and causes damages to the environment. Home security has also become an important concern due to the frequent occurrences of burglaries and home accidents. Surveillance cameras are commonly deployed to improve home security. This paper presents the design of an automatic surveillance camera application called iEye. It aims to reuse components of an old smartphone including the camera, sensors, and micr关键词: Home security;Smartphone;Mobile app;Surveillance camera;E-waste reduction

摘要: Images, which are captured in the night, have the poor quality in comparison to day light. In surveillance cameras, because of weather and other constraint images have low brightness, low contrast, and high noise. We need night vision in various sectors like automobile industry, LOC patrolling, Civil Security, Prevent accident, etc. In this paper, we try to improve image quality by the improving contrast enhancement algorithm along with developed luminance range.

摘要: The implementation of face recognition with TensorFlow deep learning uses the webcam as a surveillance camera on the Raspberry Pi, aiming to provide a sense of security to the requiring party. A frequent surveillance camera problem is that crimes are performed at certain hours, the absence of early warning features, and there is no application of facial recognition on surveillance cameras. The function of this system is to perform facial recognition on every face captured by the webcam. Use the 关键词: Face Recognition;Deep Learning;TensorFlow;Surveillance Camera;Raspberry Pi

摘要: Abstract Nuclear energy is a clean and popular form of energy, but leakage and loss of nuclear material pose a threat to public safety. Radiation detection in public spaces is a key part of nuclear security. Common security cameras equipped with complementary metal oxide semiconductor (CMOS) sensors can help with radiation detection. Previous work with these cameras, however, required slow, complex frame-by-frame processing. Building on the previous work, we propose a nuclear radiation detection关键词: nuclear radiation detection;surveillance camera;CMOS sensor;uncovered lens;convolution neural network

摘要: Trees are important natural wind engineering elements in both the urban and the agricultural contexts, but their aerodynamic description has been limited by its focus on young, flexible trees. Here, we provide a reformulation of the classical drag equation, which is also suitable for mature and wind-adapted trees. The new formulation is based on results from a full-scale experiment with focus on a solitary oak tree, for which we determined all terms in the drag equation experimentally. We also p关键词: Image analysis;Surveillance camera;Drag force;Wind–tree interaction;Tree;Vogel exponent

摘要: In order to solve the problems of small measurement range, large error and low efficiency of laboratory optical field angle testing, a high-precision, easy -operating, high-efficient, and widely used horizontal field angle test method is proposed. It comes to a conclusion that the test method can reduce the experimental error through the analysis of the principle of the field of view error and the calculation of laboratory simulation. The simulation results show that for cameras with a field of 关键词: Field of view;Surveillance camera;Wide range;Test accuracy

摘要: The global economy has been affected enormously due to the spread of coronavirus (COVID-19). Even though, there is the availability of vaccines, social distancing in public places is one of the viable solutions to reduce the spreading of COVID-19 suggested by the World Health Organization (WHO) for fighting against the pandemic. This paper presents a YOLO v3 object detection model to automate the monitoring of social distancing among persons through a CCTV surveillance camera.

摘要: Surveillance cameras are ubiquitous within modern building systems, providing a wealth of data that, to date, has not been utilized for structural health monitoring and condition assessment. In this paper, a vision-based vibration-monitoring technique is introduced, which leverages existing cameras within building structures to extract modal information and assess for damage. Cameras already installed within buildings, such as interior surveillance cameras, are used to measure structural respons关键词: Surveillance camera;Vision-based;Camera;Modal identification;Output-only;Experiments

摘要: Numerous techniques have been evolved for the detection of violence in human beings. Prior detection of human action can help to prevent and control suspicious and criminal activities. The offline video processing system has been used for post-action analysis. We address the violence detection trouble of humans in real-time visual surveillance such as punching, fighting.

摘要: We propose a video authentication scheme to verify whether a given video file is recorded by a camera device or touched by a video editing tool. The proposed scheme prepares software characteristics of camera devices and video editing tools in advance, and compares them with the metadata of the given video file. Through practical implementation, we show that the proposed scheme has benefits of fast analysis time, high accuracy and full automation.关键词: video integrity;authentication;software characteristics;video editing tool;surveillance camera

摘要: Vehicle re-identification (Re-Id) is the key module in an intelligent transportation system (ITS). Due to its versatile applicability in metropolitan cities, this task has received increasing attention these days. It aims to identify whether the specific vehicle has already appeared over the surveillance network or not. Mostly, the vehicle Re-Id method are evaluated on a single dataset, in which training and testing of the model is performed on the same dataset.

摘要: Traffic management has become one of the most complicated issues of recent times in metropolitan cities. Conventional traffic signaling systems are pre-programmed and alternate between red and green lights without any estimation of traffic. This signaling methodology leads to problems during peak hours at the intersections, where traffic ratio in a few lanes are dense when compared to others. Therefore, an efficient model is needed, which can manage the traffic flow at a certain point.

摘要: Illegal fishing is an acknowledged problem within no‐take areas (NTAs), which are frequently used as a marine conservation management tool. While gathering data on illegal fishing is difficult, it is necessary, as these data enable increased efficiency of compliance patrols, where resources are inherently limited. In particular, information about short‐term temporal variations in illegal fishing in NTAs is needed to guide management and compliance efforts.

摘要: AbstractAccurately sensing the global position and posture of vehicles in traffic surveillance videos is a challenging but valuable issue for future intelligent transportation systems. Although in recent years, deep learning has brought about major breakthroughs in the six degrees of freedom (6-DoF) pose estimation of objects from monocular images, accurate estimation of the geographic 6-DoF poses of vehicles using images from traffic surveillance cameras remains challenging.

摘要: Video analytics is a field of computer science which involves processing of videos and live video streams to gather data for obtaining domain-specific information. The traditional closed-circuit television (CCTV) system requires humans to monitor the CCTV camera streams for 24/7 which is inefficient and costly. Additionally, the existing systems work in a post-offense mechanism, that is the video streams are checked only after a crime has already taken place.

摘要: Video anomaly detection is widely applied in modern society, which is achieved by sensors such as surveillance cameras. This paper learns anomalies by exploiting videos under the fully unsupervised setting. To avoid massive computation caused by back-prorogation in existing methods, we propose a novel efficient three-stage unsupervised anomaly detection method. In the first stage, we adopt random projection instead of autoencoder or its variants in previous works. Then we formulate the optimizat关键词: Video anomaly detection; Unsupervised ensemble learning; Random projection; Surveillance camera

摘要: The purpose of this research is to confirm that moving object detection is possible from surveillance camera image using change of DCT signs. First, change of DCT signs are detected between the current frame and the background image. Then, only the changed DCT signs were inversely transformed and binarized. As a result, it was possible to detect the edge part of the moving object. In conclusion, it was found that moving object detection is possible from the change of DCT signs of the surveillanc关键词: 監視カメラ;DCT sign;動体検出;DCT符号;surveillance camera;moving object detection
