The masses of people urgently need a platform to help them identify the authenticity of network images, but the existing image forgery detection algorithms generally have high thresholds and poor real-time problems, making it difficult for the public to provide efficient detection services. Therefore, this paper proposes a cloud-based network image forgery detection system that uses B/S architecture, integrates multiple algorithms, and uses cloud computing and GPU computing technologies to improve system throughput and detection speed. Experimental results show that the system can effectively detect copy-move and splicing forgeries, and the GPU's speedup ratio reaches 6.5, which significantly improves the detection speed and throughput of the system.

Person re-identification technology is an important foundation for security, pedestrian tracking and other fields, and is the key to building a safe and smart city. In recent years, a large number of researchers have trained pedestrian re-identification networks through triplet loss, especially the triplet loss with batch hard mining (BHTri loss) has greatly improved person re-identification networks on accuracy. However, triplet loss with batch hard mining for an anchor sample only select the hardest positive sample and the hardest negative sample to calculate the loss, ignoring the influence of other samples on network parameters. In response to the above issues, this paper proposes a variant of triplet loss with batch hard mining, which is called adaptive weight triplet loss with batch hard mining. After the training dataset extracts features from the backbone network, in the phase of calculating loss, it takes the average of the sum of the distances between an anchor sample and all corresponding positive samples as a threshold, and both positive samples with an anchor point distance greater than the threshold and negative samples smaller than the threshold are retained, then based on The distance of the anchor sample is given the corresponding sample weight for calculating the loss. Compared with BHTri, mAP have improved 1.79%, 2.04%, and 1.25% respectively on the Market1501, DukeMTMC-reID and CUHK03 datasets, indicating that the proposed algorithm is effective.

This paper proposed an active disturbance rejection adaptive command filtered control (CFC) scheme for tracking control of electrohydraulic actuator subjected to both parametric uncertainties and uncertain nonlinearities. The proposed controller is developed by combining extended observer technology and adaptive CFC backstepping method. The adaptive law is used to deal with parameter uncertainty; matching uncertainties and mismatching uncertainties are estimated by two extended state observers and compensated in a feedforward way. Parameter self-adaptation can greatly reduce parameter uncertainty and ease the estimation burden of the extended state observer. CFC technology is employed to deal with the inherently complex explosion problem of classic backstepping technology. Therefore, the design of the controller avoids high-gain feedback, reduces tracking errors, and decreases online calculation burden. The proposed controller can guarantee asymptotic stability and expected control performance. Comparative simulation results are acquired to verify the tracking performance of the proposed approach.

The adversarial samples can cause the convolutional neural network model to output incorrect results. It is proposed to paste the generated adversarial sample patch on the roof of the transport vehicle to prevent aerial identification of the drone and achieve the attack on the target detection system. By producing aerial transport vehicle datasets, a YOLOv2-based target detection model is trained in the Pytorch deep learning framework, and the adversarial patch is trained by the GAN (Generative Adversarial Networks) called adversarial-yolo that can make the target detection failed. After simulation and comparison, the transport vehicle with a small adversarial patch can successfully and stably attack the target detection model, making it unable to detect the target, and the operation is flexible. The research can provide a certain reference value for the defense and camouflage methods of important ground targets against unmanned aerial intelligent detection devices.

During the operation of the low altitude radar platform, the test of electromagnetic environment from the surface is becoming more and more severe, which has directly affected the various performance of radar detection. The land clutter is not only an important component of the radar electromagnetic environment, but also an important feature of the radar electromagnetic environment, therefore, it is necessary to measure and analyze the characteristics of the land clutter. In this paper, a small unmanned aerial vehicle (UAV) is used as a carrier to carry a certain type of pseudorandom code continuous wave radar for land clutter measurement, the clutter characteristics of the measured terrain are analyzed according to the amplitude distribution, temporal correlation and spatial correlation of land clutter, so as to get the statistical feature of the land clutter under different measurement conditions.

It is of great significance for the promotion and popularization of tourism ecommerce to study the factors influencing the adoption of mobile hotel reservation. From the perspective of user experience, taking TTF and UTAUT as the theoretical framework, four external variables including situational awareness, user experience, perceived risk and perceived cost are added to build a mobile hotel reservation adoption model. Based on the fact that senior college students have more travel needs, this paper takes college students as an example to make an empirical analysis. The results show that: task technology matching, situational awareness, effort expectation and performance expectation have a significant impact on user experience, and then affect user behavior intention; social impact, perceived risk and perceived cost also have a significant impact on user behavior intention, among which social impact has the strongest impact on college students' mobile hotel reservation intention. Combined with the analysis of empirical results, some suggestions are put forward for the development and operation promotion of mobile hotel reservation application.
