To solve this problem, we propose a two-stage CBIR algorithm in the paper. Firstly, considering the strong ability of Convolutional Neural Network (CNN) in feature extraction, CNN-based models are established to extract high-level features for image retrieval. Secondly, Ensemble Learning (EL) framework is employed to form a new CBIR algorithm. Finally, experiments are implemented to compare the performance of the proposed algorithm with traditional algorithms. The results show that our algorithm has better image retrieval capability and stronger generalization ability.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117326423","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}

Different from the existing works, we propose an opportunistic user scheduling (OUS) scheme based on SNR-threshold feedback. By assuming that the satellite link and the terrestrial links undergo Shadowing-Rician fading and Rayleigh fading, respectively, we first obtain probability density function of the output signal-to-noise ratio (SNR) with the proposed scheduling scheme. Then, we derive analytical expression for the ergodic capacity (EC) of the considered system. Finally, numerical results prove that the OUS scheme with SNR-threshold based feedback can reduce the amount of feedback greatly, and the system with proposed scheme can achieve the same capacity as that without feedback threshold.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117197981","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}
