Anomaly detection is a challenging task in the field of intelligent video surveillance. It aims to identify anomalous events by monitoring the video captured by visual sensors. The main difficulty of this task is that the definition of anomalies is ambiguous. In recent years, most anomaly detection methods use a two-stage learning strategy, i.e., feature extraction and model building. In this paper, with the idea of refactoring, we propose an end-to-end anomaly detection framework using cyclic consistent adversarial networks (CycleGAN). Dynamic skeleton features are used as network constraints to alleviate the inaccuracy of feature extraction algorithms of a single generative adversarial network. In the training phase, only normal video frames and the corresponding skeleton features are used to train the generator and discriminator. In the testing phase, anomalous behaviors with high reconstruction errors can be filtered out by manually set thresholds. To the best of our knowledge, this is the first time CycleGAN has been used for video anomaly detection. Experimental results on challenging datasets show that our method can accurately detect anomalous behaviors in videos collected by video surveillance systems and is comparable to the current state-of-the-art methods. 相似文献

Smart materials with electrically responsive characteristics and devices relying on different electrostatic effects can be directly driven by triboelectric nanogenerators (TENGs). The open circuit voltage from a TENG can easily reach thousands of volts with a separation distance of a few millimeters and this high output voltage can be used to effectively drive or control some devices with high internal resistance. This kind of combination is the most straightforward way for achieving a self‐powered smart system. Hence, a detailed survey of electrically responsive materials and devices that can be successfully combined with TENG is summarized, including dielectric elastomers, piezoelectric materials, ferroelectric materials, electrostatic manipulators, electrostatic air cleaners, and field emission and mass spectrometers. Moreover, key factors in determining suitable materials or devices to work with TENG are clarified and an in‐depth discussion of the current challenges related to these combined systems is provided. With the cost‐effectiveness and simple manufacturing process, these TENG‐based composite systems have great application prospects in the field of smart mechanics, human–machine interaction systems, intelligent storage systems, self‐powered microfluidic chips, portable mass spectrometers, and so on. 相似文献

This paper will first briefly survey the existing impact of multimedia information retrieval (MIR) in applications. It will then analyze the current trends of MIR research which can have an influence on future applications. It will then detail the future possibilities and bottlenecks in applying the MIR research results in the main target application areas, such as the consumer (e.g., personal video recorders, web information retrieval), public safety (e.g., automated smart surveillance systems), and professional world (e.g., automated meeting capture and summarization). In particular, recommendations will be made to the research community regarding the challenges that need to be met to make the knowledge transfer towards the applications more efficient and effective. It will also attempt to study the trends in the applications which can inform the MIR community on directing intellectual resources towards MIR problems which can have a maximal real-world impact. 相似文献

Increased recognition of the importance of sustainable development is posing new challenges for industry. A systems approach provides a framework for reconciling the needs of sustainable development with all of the other demands on industry. The computer industry has been chosen to illustrate the application of a systems approach to green design in industry on account of both its increasing economic importance and the increasing role of computers in society. A brief discussion of the current environmental impact of the computer lifecycle is presented to set the context for the discussion of systems approaches to green design, and a survey of existing systems-based design approaches and discussion of their application to the computer industry is given. A number of examples are presented to illustrate the advantages and application of a systems approach to green design, and the principles as well as some of the main issues in a systems approach to green design in the computer industry are discussed 相似文献

For the robust detection of pedestrians in intelligent video surveillance, an approach to multi-view and multi-plane data fusion is proposed. Through the estimated homography, foreground regions are projected from multiple camera views to a reference view. To identify false-positive detections caused by foreground intersections of non-corresponding objects, the homographic transformations for a set of parallel planes, which are from the head plane to the ground, are applied. Multiple features including occupancy information and colour cues are extracted from such planes for joint decision-making. Experimental results on real world sequences have demonstrated the good performance of the proposed approach in pedestrian detection for intelligent visual surveillance. 相似文献

Intelligent visual surveillance for road vehicles is the key to developing autonomous intelligent traffic systems. Recently, traffic incident detection employing computer vision and image processing has attracted much attention. In this paper, a probabilistic model for predicting traffic accidents using three-dimensional (3-D) model-based vehicle tracking is proposed. Sample data including motion trajectories are first obtained by 3-D model-based vehicle tracking. A fuzzy self-organizing neural network algorithm is then applied to learn activity patterns from the sample trajectories. Finally, vehicle activity is predicted by locating and matching each partial trajectory with the learned activity patterns, and the occurrence probability of a traffic accident is determined. Experiments show the effectiveness of the proposed algorithms. 相似文献

In automatic video surveillance (VS) systems, the issue of authenticating the video content is of primary importance. Given the ease with which digital images and videos can be manipulated, practically they do not have any value as legal proof, if the possibility of authenticating their content is not provided. In this paper, the problem of authenticating video surveillance image sequences is considered. After an introduction motivating the need for a watermarking-based authentication of VS sequences, a brief survey of the main watermarking-based authentication techniques is presented and the requirements that an authentication algorithm should satisfy for VS applications, are discussed. A novel algorithm which is suitable for VS visual data authentication is also presented and the results obtained by applying it to test data are discussed 相似文献

A framework for building intelligent manufacturing systems 总被引:1,自引:0,他引:1

The paper describes a systematic approach to design and development of software for intelligent manufacturing systems. The approach is based on a multilevel, general object oriented model of intelligent systems. Current methods and software design and development tools for intelligent manufacturing systems either stress particular components of intelligence (e.g., high level domain expertise, or learning capabilities, or fuzziness of decisions), or their domain dependence (e.g., monitoring and control systems, or CAPP systems). It is usually difficult to make extensions of such methods and tools, nor is it easy to reuse their components in developing intelligent manufacturing systems. Considerable efforts are being dedicated to the development of interoperable software components, distributed object environments, and flexible and scalable applications to overcome some of these problems. The approach described in the paper starts with a well founded software engineering principle, making clear distinction between generic, low level intelligent software components, and domain-dependent, high level components of an intelligent manufacturing system. It is extensible and adjustable. It also suggests some steps toward design of future software development tools for intelligent manufacturing systems. Several intelligent systems have been developed using the approach. One of these systems, in the cement manufacturing domain, is briefly overviewed, illustrating how the approach is used in practice. Finally, some informal discussion on the performance and complexity of the approach is presented 相似文献
