Most studies of video-based heart rate measurement usually use a single denoising algorithm such as principal component analysis (PCA) or independent component analysis (ICA) to reduce noise in original signal. Using only one single denoising algorithm usually can not achieve satisfactory results, because each denoising algorithm has its shortcomings. To deal with this problem, this study has proposed to combine the following three denoising algorithms of wavelet transform (WT), PCA and ICA in different ways for noise removal in the original heart rate signal. The denoising performance is evaluated by root mean square error (RMSE) and mean absolute error (MAE). The experimental results have shown that the measurement accuracy of combined algorithms is higher than that of single algorithm. The proposed combined denoising algorithm in this study can improve accuracy and enhance stability of heart rate measurement, which is of practical significance for the application of non-contact heart rate measurement technology.","PeriodicalId":123022,"journal":{"name":"2022 3rd Information Communication Technologies Conference (ICTC)","volume":"394 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115309935","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, most of the existing authentication schemes are based on password, in which users need to remember the complex passwords and change them frequently. In addition, the great majority of authentication schemes have security defects. Through the analysis of the scheme proposed by Haq et al., we find that it is difficult to resist the key compromise impersonation attack. Therefore, an improved two-factor multiserver authentication scheme without password is proposed. The perfect combination of the user’s biological characteristics and the PUF’s physical characteristics enhances the practicality and efficiency of the solution. Security analysis of the proposed scheme shows that it can resist various known security attacks.","PeriodicalId":123022,"journal":{"name":"2022 3rd Information Communication Technologies Conference (ICTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130805252","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}

Although there are numerous performance analysis and optimization works for this technology, the mechanism of error formation is still unclear, and it is still very challenging to optimize the localization performance, especially the relationship between the site survey and localization error is very complicated, and the sampling interval not only affects the localization error but also determines the survey workload. To address the above problems, this paper obtains the relationship between localization error and sampling interval in two-dimensional scenes based on Monte Carlo method, and then defines a survey cost formula based on multi-objective optimization theory to weigh localization error and site survey workload, and then obtains the optimal sampling interval. The simulation results prove the correctness of this study, which is consistent with the previous conclusions obtained through experiments.","PeriodicalId":123022,"journal":{"name":"2022 3rd Information Communication Technologies Conference (ICTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128995120","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}

The framework learns to fuse features from different views to improve object detection accuracy on the autonomous vehicle. To evaluate the proposed method, we build a new synthetic dataset created in two driving scenarios (a Roundabout and a T-junction).

There are few existing evolution models of public opinions to distinguish opinion formation from opinion expression. The expression of individual opinions is often affected by the social environment. Meanwhile, individuals express their opinions under social pressure from other individuals. In order to enhance the power of predicting public opinions, this paper introduces individual inertia to measure the degree of individuals’ adherence to their own opinions. It also introduces social pressure to modify the individual opinions. Integrated with individual inertia, social pressure and HegselmannKrause model, a modified Hegselmann-Krause model is proposed. Simulation experiments show that the proposed individual inertia and social pressure affect the evolution of opinions in social networks. The modified Hegselmann-Krause model can promote the formation of consensus by changing the individual inertia and social pressure to a certain extent.","PeriodicalId":123022,"journal":{"name":"2022 3rd Information Communication Technologies Conference (ICTC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122859983","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}

The diversification in device types and differentiation in equipment performance leads to the heterogeneity of network structure and multi-dimensionality of resources. And the satellite network is highly dynamic and network topology changes frequently, resulting in time-varying. Therefore, there are a stronger demand to meet the requirements of network structure characterization, resource dimensional expansion and the time-varying presentation in integrated network. In this paper, a multi-dimensional resource model named space-time resource tree (S-TRT) is proposed to deal with these problems. S-TRT is composed of two independent tree structures: node tree and node-resource tree. Node tree represents the heterogeneous characteristics of integrated network by the hierarchy of the tree structure. Node- resource tree uses the number of sub nodes, which is unlimited in N-ary tree, to adapt to the expansion of resource dimensions. Then use a series of basic operations such as node inserting, updating and combining to realize the time-varying characteristics of resources in integrated network. Finally, the simulation results show that compared with ETSDSnapshot and ETEG models, the complexity of the S-TRT model is reduced to O(logn) and the time-varying cost is reduced by about 20% over a period of time.","PeriodicalId":123022,"journal":{"name":"2022 3rd Information Communication Technologies Conference (ICTC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132851434","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}
