Deep learning has achieved great success in many fields, such as image classification and target detection. Adding small disturbance which is hard to be detected by the human eyes to original images can make the neural network output error results with high confidence. An image after adding small disturbance is an adversarial example. The existence of adversarial examples brings a huge security problem to deep learning. In order to effectively defend against adversarial examples attacks, an adversarial example defense method based on image reconstruction is proposed by analyzing the existing adversarial examples attack methods and defense methods. Our data set is based on ImageNet 1k data set, and some filtering and expansion are carried out. Four attack modes, FGSM, BIM, DeepFool and C&W are selected to test the defense method. Based on the EDSR network, multi-scale feature fusion module and subspace attention module are added. By capturing the global correlation information of the image, the disturbance can be removed, while the image texture details can be better preserved, and the defense performance can be improved. The experimental results show that the proposed method has good defense effect.

In response to the problem that the current image processing technology and underwater target recognition algorithms are not yet mature enough in the field of underwater archaeology, this article innovatively applies object detection and underwater image clarity technology to the field of underwater archaeology. We propose a method for detecting and recognizing underwater cultural heritage based on optical devices. The method includes ocean image preprocessing and underwater cultural heritage object recognition based on YOLO V4. The results of experiments demonstrate that the proposed method can effectively and accurately detect and recognize targets in the underwater cultural heritage scene, and the clear image of the underwater relics after image preprocessing can better assist archaeologists in observing the species and distribution of samples in the real scene.

There are still challenges in the field of video understanding today, especially how to use natural language to describe the visual content in videos. Existing video encoder-decoder models struggle to extract deep semantic information and effectively understand the complex contextual semantics in a video sequence. Furthermore, different visual elements in the video contribute differently to the generation of video text descriptions. In this paper, we propose a video description method that fuses instance-aware temporal features. We extract local features of instances on the temporal sequence to enhance perception of temporal instances. We also employ spatial attention to perform weighted fusion of temporal features. Finally, we use bidirectional long short-term memory networks to encode the contextual semantic information of the video sequence, thereby helping to generate higher quality descriptive text. Experimental results on two public datasets demonstrate that our method achieves good performance on various evaluation metrics.

To address the issue of high cost and low efficiency in the manual sorting of apples, we proposed an improved apple classification method based on the AlexNet architecture. The algorithm added a batch normalization layer after each convolutional layer in the network structure to speed up the model's training process. Furthermore, we replaced the fully connected layer with a global average pooling layer to reduce the number of training parameters and save model training time. To improve the algorithm's robustness, we also performed data augmentation on the training samples before validating the algorithm to obtain an expanded dataset. Experimental results showed that the improved AlexNet network shortened the training time by 0.54%, increased the testing speed by 2.5%, and improved the accuracy by 1.12% compared to the original AlexNet network. Moreover, the training time of the improved AlexNet network was lower than that of other networks (AlexNet, ResNet50, Vgg16). The improved AlexNet network can efficiently and quickly classify apples and promote the automation of apple classification.

Based on the least squares support vector machine (LSSVM) in machine learning, this study uses the information provided by ADS-B, such as heading, position and altitude, combined with the regulations and conflict protection zones in actual operation, to classify the occurrence and severity of flight conflicts under the same moment, i.e., to perform multiple classifications, and uses a hybrid optimization algorithm of genetic + particle swarm to optimize this support vector machine model, and proposes A very efficient and accurate real-time flight conflict detection model is proposed. Finally, simulation analysis shows that the support vector machine is faster and more accurate than the traditional SVM, and has excellent conflict detection capability, and by differentiating the classified conflict levels and performing supervised learning, it can provide accurate warnings for upcoming flight conflicts, which can draw early attention of ATCs and provide a basis for the next flight conflict resolution. Eventually, the conflict detection model is expected to be compatible to airborne and ground surveillance equipment, which can significantly improve the safety of flight activities and has a broad application prospect and important research value.

In order to solve the multi-vehicle mutual occlusion problem encountered in 3D target detection by self-driving vehicles, this paper proposes a monocular 3D detection method that includes dynamic occlusion determination. The method adds a dynamic occlusion processing module to the CenterNet3D network framework to improve the accuracy of 3D target detection of occluded vehicles in the road. Specifically, the occlusion determination module of the method uses the 2D detection results extracted from target detection as the occlusion relationship determination condition, wherein the method of changing the occlusion determination threshold with the depth value is introduced. Then the occlusion compensation module is used to compensate and adjust the 3D detection results of the occurring occluded vehicles, and finally the 3D target detection results are output. The experimental results show that the method improves the accuracy of both vehicle center point detection and 3D dimensional detection results in the case of long-distance continuous vehicle occlusion. And compared with other existing methods, the accuracy of 3D detection results and bird's-eye view detection results are improved by 1%-2.64% in the case of intersection over union of 0.5. The method can compensate for the occluded vehicles in 3D target detection and improve the accuracy

In order to show the transport conditions of goods on different roads and provide more real and three-dimensional transport information for situation inference users, this paper proposes a simple and PID controlled three-dimensional simulation method for truck formation based on Unreal Engine. Firstly, based on the basic theory of automatic control [1] , the longitudinal lollipop controller and the transverse PID controller are designed respectively based on the lollipop control and PID control ideas, and the perception-decision framework is combined to realize the automatic driving of the truck along the spline line on the road. On this basis, a truck controller is designed to realize the truck formation driving with high recovery degree based on the leader-follower strategy. The results show that the truck based on PID control can accurately drive along the road line. With the cooperation of truck formation controller, the whole process of formation, maintenance and driving of truck formation can be basically restored.
