Since the existing methods do not consider the terrain obscured effect, a 3D sensor deployment method based on viewshed and pattern search is proposed in this paper. Firstly, the problem is mathematically described by using the sensor detection model and terrain obscured effect. Secondly, the detailed implementation steps of the method are given. The viewshed algorithm is used to calculate the coverage rate of the sensors and establish the objective function. The pattern search algorithm is used to optimize the deployment location of sensors. Finally, the proposed method is verified by simulation. The simulation results show that the method can plan the least sensors on the surface of a given 3D complex terrain to reach a certain coverage rate, and avoid falling into the local optimization.","PeriodicalId":105724,"journal":{"name":"Proceedings of the 2022 International Conference on Pattern Recognition and Intelligent Systems","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125145832","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}

Besides, low-contrast military vehicles are more difficult to be spotted in the field. Therefore, we create a dataset of military vehicles that consists of a training set and two different test sets, and we suggest an efficient method for image data augmentation that is mostly based on style transfer. Specifically, the process of data augmentation contains targets mask generation, style transfer, and details addition, and doesn't need extra annotation work. In the experimental part, YOLO v5s is applied to verify the efficacy of our method. Our method enables us to improve the precisions by 0.101 and 0.134 in the high-contrast situation, and achieve the precisions of 0.729 and 0.515 in the low-contrast situation when using single-style stylized images dataset and multi-style stylized images dataset respectively, in experiments. The results suggest that our method can reduce overfitting and show a rather satisfactory performance on our self-made dataset.","PeriodicalId":105724,"journal":{"name":"Proceedings of the 2022 International Conference on Pattern Recognition and Intelligent Systems","volume":"79 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130840461","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}

Yet, how to accurately predict the local logistics demand remains further improvement. To deal with it, this paper proposed an KPCA-GA-ELM approach which firstly introduces an extreme learning machine (ELM) approach to build the forecasting model, then incorporate both kernel principal component analysis (KPCA) and genetic algorithm (GA) into it. Taking Shanghai's regional logistics demand prediction as an example, two principal components affecting regional logistics demand are extracted by KPCA, ELM is then used to develop a regional logistics demand forecast model, and the genetic algorithm was applied to make the ELM model arguments be better to avoid the impact of strong randomness in parameter selection on model prediction performance and generalization ability. The results indicate that the accuracy is significantly improved comparing it with other two models. Such model then can be used as the demand forecasting and estimation approaches to estimate the demand of other industries in a region.","PeriodicalId":105724,"journal":{"name":"Proceedings of the 2022 International Conference on Pattern Recognition and Intelligent Systems","volume":"86 35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131077269","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}

At the moment, it is difficult to use the same set of equipment to recognize features and defects in three dimensions on the complicated surface of the rail. The ring stroboscopic illumination system was devised in this study based on the features of the complicated surface of the rail, and the whole surface image of the rail was gathered by seven linear scan cameras. Create a point cloud model of the rail surface, then re-calibrate the light source's direction based on the rail's fundamental geometry. The normal vector of the rail surface is then calculated to appropriately recreate the 3D surface of the rail. This research provides a method for eliminating gradient error in the direction of motion by using point cloud registration to increase the accuracy of 3D rail surface reconstruction. The breadth and depth of surface defects were assessed using the rail surface's rebuilt 3D model, and the average relative inaccuracy was 7.23%. The Yolo deep learning algorithm is utilized for character identification, and recognition accuracy may reach more than 99%. Experiments suggest that the approach may be used to detect rail surface defects in three dimensions on time. The method not only could be beneficial to the monitoring and optimization of the quality in the rail manufacturing process, but also establish a solid foundation for increasing the safety of high-speed trains.","PeriodicalId":105724,"journal":{"name":"Proceedings of the 2022 International Conference on Pattern Recognition and Intelligent Systems","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127858319","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}

According to the actual situation of D & A system, this paper establishes the key performance indicators. In the process of processing Tianjin port, we extract key indicators from the data types they regularly process to build a D & A system. At the same time, we use the resources of the school library to collect and download excellent literature in the field of corporate performance research methodology to determine which factors need to be considered. In order to analyze the relationship between various influencing factors and enterprise performance and the size of influencing factors, the weight matrix is established by analytic hierarchy process. In order to judge which index has a greater impact on the company's performance, we use the Delphi method to evaluate the relative importance of the indexes and obtain an evaluation matrix.

Sometimes one particular classifier perform better than others for a given dataset, while the performance may worse than other classifiers for other datasets. Many studies have shown that classifier ensemble method is a more effective approach. a multi-level weighted voting classification algorithm based on the combination of classifier ranking and Adaboost algorithm is proposed in this paper.. Four feature selection methods are used to select the features, and then seven commonly used heterogeneous classifiers are used to select five classifiers and calculate their ranks, and then AdaBoost is used to boost the performance of the selected base classifiers and calculate the updated F1 and ranks. The effects of ensemble framework Majority Voting (MV), Weighted Voting (WV), Layered Majority Voting (LMV), Layered Weighted Voting (LWV) were all evaluated from the aspects of accuracy, sensitivity, specificity, and G-measure. In addition, the ROC curves of each ensemble framework are plotted for analysis, and the outcome of the experiments shows that our presented method achieves significant results on Australian credit score data and some progress on the German loan approval data.","PeriodicalId":105724,"journal":{"name":"Proceedings of the 2022 International Conference on Pattern Recognition and Intelligent Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129074829","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}
