However, the detection effect of these methods on cloud edge regions and thin cloud regions is generally poor, mainly because these confusing regions account for a small proportion but have problems of greater intra-class inconsistency and stronger inter-class similarity. To this end, we propose a novel two-branch cloud detection network named TBNet, which focuses more on cloud edge regions by adding a boundary prediction branch to the semantic segmentation branch and jointly optimizing parameters. Specifically, the boundary prediction branch is designed to be shallow and pooling-free to preserve details as much as possible while controlling the computational cost of the model. Further-more, Fusion Module and Semantic Enhanced Module are proposed and used for the interaction between the semantic segmentation branch and the boundary prediction branch. FM can provide the necessary high-level features for the boundary prediction branch, and SEM can provide multi-scale contextual information to enable detection of clouds with different characteristics. In the experiments, our method obtains 97.23% accuracy, 93.20% F1-score, 91.46% Kappa, and 91.92% mIoU on the GF-1 wide field-of-view (WFV) satellite imagery dataset.","PeriodicalId":175659,"journal":{"name":"2022 2nd International Conference on Frontiers of Electronics, Information and Computation Technologies (ICFEICT)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114982743","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}

Aiming at these problems, this paper proposes an UKF algorithm based on multi-dimensional adaptive factors (SMA-UKF). Firstly, the sufficient conditions for establishing strong tracking UKF are expounded combined with UKF algorithm and strong tracking filtering principle. Furthermore, some multi-dimensional adaptive factors are introduced into the single-step forward prediction covariance matrix, and their calculation methods are designed respectively. Finally, the effects of SMA-UKF, strong tracking UKF algorithm (ST-UKF) and UKF algorithm in target tracking are simulated and compared under the condition that the system model and noise are inaccurate. The results show that SMA-UKF can automatically judge and adaptively adjust the process noise, and achieve good tracking of the target.","PeriodicalId":175659,"journal":{"name":"2022 2nd International Conference on Frontiers of Electronics, Information and Computation Technologies (ICFEICT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121034077","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}

In this paper, we applied a vector network analyzer (VNA) to the THz-CT-CW system to replace the transceiver devices and omit the optical chopper for improving the transceiver device integration. And learning from the free-space method system, we adopt 2 ellipsoid mirrors to the THz-CT-CW system to directly focus the emitted wave on the sample for reducing the number of lenses/mirrors used in the traditional system. Finally, we verified the feasibility of the proposed system according to the imaging results from the experiment.

In this work, we first explore the mono multi-instrument separation problem from a 3D visu-al perspective, combining multimodal features learned from audio and 3D point cloud patterns together. Next, we use 3D sparse convolution to extract sparse tensor features of the point cloud, and use a self-attention mechanism to obtain effective spatial and color information in a series of discrete points. A combination of dense join and dilation convolution unravels the different sound source information in the sound spectrogram signal. The fusion module fuses the features extracted from the visual model and the corresponding feature information obtained from the audio model to finally perform audio source separation. The results show that the 3D point cloud feature representation of musical instruments can better assist audio source separation, which is more applicable to 3D realistic conditions. It also shows that the use of natural synchronization of 3D visual and audio allows the application to better solve problems in 3D virtual or augmented reality applications.","PeriodicalId":175659,"journal":{"name":"2022 2nd International Conference on Frontiers of Electronics, Information and Computation Technologies (ICFEICT)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125961257","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}

High quality panoramic video is often achieved by using high resolution and high framerates and due to these features, delivering high quality panoramic video has considerable data flow, consuming large data bandwidth and computing power. To address this problem, we introduce a novel streaming method, reducing streaming data flow by splitting panoramic video into blocks and selectively deliver the blocks users see in the panoramic video stream, exploiting the fact that the viewer has a limited field of view. Results show that our method effectively reduces the bandwidth when delivering panoramic video without compromising the quality of the panoramic video at the same time.","PeriodicalId":175659,"journal":{"name":"2022 2nd International Conference on Frontiers of Electronics, Information and Computation Technologies (ICFEICT)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114555494","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}

Hybrid beamforming becomes a cost-effective solution for massive MIMO beamforming, though there is usually trade-off between performance and computation complexity. How to design a hybrid beamforming method to achieve good performance while with a low complexity becomes a challenge. In this paper, we propose such a method based on eigenvalue decomposition and regularized channel diagonalization (EVD-RCD). Without knowing prior knowl-edge of the array geometry, the proposed algorithm not only achieves high spectral efficiency with low complexity, but also has strong robustness to deal with different antenna array geometry, imperfect CSI and quantized phase shifter.","PeriodicalId":175659,"journal":{"name":"2022 2nd International Conference on Frontiers of Electronics, Information and Computation Technologies (ICFEICT)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116197994","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 energy transactions between electric vehicles and the power grid is completed by the aggregators. Energy transactions are generally completed through open wireless communication networks, which are vulnerable to network attacks such as eavesdropping, impersonation attack, etc. Data transmission in the V2G networks requires to verify the identity of each communication entity to achieve confidential communication. The realization of confidential communication can enhance the security of energy transactions. Key agreement is a key technique to solve this problem. Therefore, we propose a lightweight anonymous key agreement scheme for V2G networks. For efficiency, we hire a data center to assist electric vehicles and aggregators in our key agreement scheme.
