Several NeRF variants have been proposed to improve rendering accuracy and reconstruction speed. One of the most significant variants, TensoRF, uses a 4D tensor to model the radiation field, resulting in improved accuracy and speed. However, reconstruction quality remains limited. This study presents an improved TensoRF that addresses the aforementioned issues by reconstructing its multilayer perceptron network. Increasing the number of neurons in the input and network layers improves the render accuracy. To accelerate the reconstruction speed, we utilized the Nadam optimization algorithm and the RELU6 activation function. Our experiments on various classical datasets demonstrate that the PSNR value of the improved TensoRF is higher than that of the original TensoRF. Additionally, the improved TensoRF has a faster reconstruction speed (≤30min). Finally, we applied the improved TensoRF to a self-made industrial dataset. The results showed better global accuracy and local texture in the reconstructed image.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141377874","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}

With the continuous changes in the pipeline network, the urban water supply network has formed a very complex spatial information system. Due to the difficulty in accurately obtaining information about the water supply network and the traditional manual drawing, manual statistics, and manual analysis management mode which cannot handle the gradually complex information of the network, it is currently very difficult to maintain the network. This article analyzes the current situation of China's urban water supply network. Based on the problems of low information query efficiency and errors in network analysis processes, a water supply network WebGIS management system was developed based on database and GIS technology. The system has a total of 17 functions divided into five modules according to function type: display configuration, data queries, information statistics, network analysis, and map printing. The system uses a spatial database to solve the problem of processing complex network information, and its query function can quickly search for network information. By setting conditions, data filtering can be achieved, greatly improving the efficiency of information retrieval. This system uses GIS technology to visualize the water supply network and provides various click events, making the system interactive and improving the efficiency of information retrieval. In terms of spatial analysis, this article found that the water supply network can be represented by a graph, and algorithms from graph theory can be used to search for pipelines and nodes in the network. Therefore, this system has implemented two major functions of connectivity analysis and valve closing analysis in the network analysis module using Dijkstra's algorithm and breadth-first search algorithm respectively. This system can bring great convenience to the daily maintenance of the water supply network and reduce the error rate of maintenance work. Relevant departments of the government can achieve efficient management of the urban water supply network through the system's data query and network analysis functions.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141378934","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}

However, existing cloud services are concentrating on improving the data storage amount and ignore the privacy data protection for data owners. In order to protect the privacy data, data owners may encrypt the information and then upload to the cloud servers. Cloud server cannot guarantee the encryption data are not at-tacked or modified by malicious attackers. In this paper, we propose a novel symmetric encryption algorithm to encrypt the privacy data for users and generate the checks for cloud servers and guarantee the privacy cannot be modified and lost by system errors. From our extensive experimental, we can conclude that our proposed model can achieve the protection of privacy by simulating the different attacks with reasonable response period. Furthermore, we compare our model with existing encryption methods and evaluate the effectiveness performance.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141376414","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}

{"title":"MCPKI-based certificate chain extension scheme for vTPM","authors":"zhentao xiao, Pan Dong","doi":"10.1117/12.3031946","DOIUrl":"https://doi.org/10.1117/12.3031946","url":null,"abstract":"To meet the trust requirements of complex environments such as cloud platforms, physical trust modules are often virtualized into virtual Trusted Platform Module (vTPM) to function as the root of trust for each virtual machine or container. In remote attestation, vTPM utilize hardware-TPM-based certificate chain extension schemes to ensure its trustworthiness. Existing vTPM certificate chain extension schemes must turn to Privacy Certificates Authority (PCA) for new certificate during every attestation, however, result in excessive computational and communication overheads. To address this issue, this paper proposes a vTPM certificate chain extension scheme based on Multi-Certificate Public Key Infrastructure (MCPKI). This scheme allows unsigned sub-certificates to have the same legitimacy and identity as the root certificate through certificates correlation. In this way, vTPM can have multiple certificates with valid identity and only need to apply to PCA once, which reduces the performance loss caused by repetitive validation in traditional certificate chain extension schemes and enhances the efficiency of Privacy CA certificate issuance. Furthermore, certificate generation is handled by the local vTPM, reducing communication overheads. A new trusted third-party Verification Certificate Authority (VCA) is introduced to share the validation workload of Privacy CA and reduce the reliance on Privacy CA in certificate chain extension. The experiment results demonstrate that this scheme outperforms traditional certificate chain extension schemes in scenarios with multiple certificates requirement.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141377662","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}

{"title":"Multiview stereo reconstruction based on context-aware transformer","authors":"Zhaoxu Tian","doi":"10.1117/12.3032052","DOIUrl":"https://doi.org/10.1117/12.3032052","url":null,"abstract":"This paper tackles the challenges inherent in existing Multi-View Stereo (MVS) methods, which often struggle with scenes that have repetitive textures and complex scenarios, leading to reconstructions that lack quality, completeness, and accuracy. To address these issues, we introduce a novel deep learning network, Clo-PatchmatchNet, which leverages context-aware Transformers for enhanced performance. The network's architecture starts with a feature extraction module that processes image features. These features are then input into a learnable Patchmatch algorithm, creating an initial depth map. This map undergoes further refinement to yield the final, detailed depth map. A key innovation in our approach is the integration of a context-aware Transformer block, known as Cloblock, into the feature extraction stage. This allows the network to effectively capture both global contextual information and high-frequency local details, enhancing feature matching across various views. Our experimental evaluations, conducted on the Technical University of Denmark (DTU) dataset, reveal that Clo-PatchmatchNet outperforms the traditional PatchmatchNet by achieving a 2.5% improvement in reconstruction completeness and a 1.2% increase in accuracy, resulting in an overall enhancement of 1.7%. Moreover, when compared to other contemporary methods, our proposed solution demonstrates superior performance in terms of both completeness and overall quality, marking a significant advancement in the field of 3D reconstruction.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141377024","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}

Due to the limitation of the initial design, BGP prefix hijacking is a kind of BGP security problem that needs to be solved urgently. This paper proposes a BGP prefix hijack detection algorithm based on Multiple Origin AS (MOAS) event feature, discovering and restoring MOAS events from BGP packets, and creating an event matrix for MOAS events based on the changes of source AS observed from different observation points over time. According to the MOAS event matrix, the eigenvalue of the event is calculated from the perspective of the overall probability of the event and the local visibility of the observation point. Finally, the characteristic value of the MOAS event is compared with the exception event threshold to determine whether the event is an exception event, and then the BGP prefix hijacking is found. Compared with the prefix hijacking detection algorithm based on source AS validity, the detection results of this algorithm have higher accuracy. This method is more practical in detecting prefix hijacking according to the characteristics of the event itself.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141379271","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}
