The indicator weights were assigned through the classic entropy weight method, and the topsis (approximate ideal solution sorting method) was used to calculate and rank the operation performance indicators of 6 urban rail transit. The obstacle degree model theory was used to analyze the indicators that affect the urban rail transit operation performance. Our research method can be used as an important reference for domestic urban rail transit operating enterprises and industry management, and provide a new method and idea for urban rail transit operation performance evaluation.","PeriodicalId":178054,"journal":{"name":"2020 5th International Conference on Information Science, Computer Technology and Transportation (ISCTT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126002860","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}

A signal processing method based on sparse maximum correlated kurtosis deconvolution (SMCKD) is proposed. Firstly, the sparse representation is used to extract the internal signal characters. Meanwhile, a sparse representation redundancy dictionary covering the knock features is established. Secondly, the maximum correlation kurtosis deconvolution (MCKD) is used to identify the knock features and eliminate the irrelevant features. Therefore, the knock state can be accurately distinguished. An engine knock intensity index based on SMCKD is also presented. And the knock intensity can accurately distinguish normal combustion, light knock and strong knock. It is verified that the method of extracting knock feature and the evaluation index of knock intensity presented in the paper have a certain value in engineering application.","PeriodicalId":178054,"journal":{"name":"2020 5th International Conference on Information Science, Computer Technology and Transportation (ISCTT)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121531659","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}

Therefore, dehazing has become a challenging task in many fields. By combining the quadtree atmospheric light estimation model with the guided filtering algorithm, this paper proposes an image enhancement algorithm, which can significantly improve the image contrast and preserve the details. This method can significantly improve color image and gray image without prior information. The multi-scale decomposition module provides basic image and detail image for the subsequent smoothing module and enhancement module. Through the atmospheric light intensity estimation algorithm and transmittance estimation algorithm described above, the accuracy of image restoration can be significantly improved. The details of the image can be saved by processing the residual image by guided filtering algorithm. Finally, the final image can be obtained by color correction algorithm.","PeriodicalId":178054,"journal":{"name":"2020 5th International Conference on Information Science, Computer Technology and Transportation (ISCTT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131269909","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}

Since the development of the R-CNN model and various improvements that follows, it is now an easy task to separate objects from the environment. For 3d reconstruction, Mesh R-CNN and PiFUHD render objects close to their original geometry, and this leads us to develop a 3d object reconstruction system that can integrate and improve its performance based on two models. We find that Mesh R-CNN can be improved with the newest PointRend model that generates more accurate shapes than Mask R-CNN on which Mesh R-CNN is based, and we reach the conclusion that a Monocular Instance Level 3D Object Reconstruction is fully feasible. document is a “live” template.
