Firstly, according to the illuminance-reflection imaging model, we adopt a bilateral filtering method to decompose the brightness into illuminance component and reflection component. Secondly, an adaptive gamma correction function is constructed, which can dynamically adjust the illuminance component. In the reflection component processing, an improved morphological operation is proposed to denoise and enhance the image details. Finally, we combine the illumination component with the reflection component to get the enhanced panoramic image. The experimental results show that the proposed algorithm can improve the effect of non-uniform illumination on the panoramic image, and can obtain better image contrast, detail information and visual effect.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129196958","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, the design of the metamaterial aperture and the requirement of the coincidence imaging are still disconnected theoretically. In this paper, we attempt to present the problems in the connection of the metamaterial aperture design and the coincidence imaging requirement. Firstly, the property of the metamaterial cells depends on the structure, which is hard to be modeled in the aperture design. Then, the physical constraints, which should be considered in the requirement of the coincidence imaging, are hard to be given. Finally, the number of the test modes that contained in the aperture is hard to evaluate in theory. We believe the presented problems can be solved in the next few years.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117163632","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}

How to accurately identify communication modulation signals under low SNR environment has become a hot topic in current research. Fractal is an effective tool to describe the geometric irregularity and geometric scale characteristics, and feature extraction of signals has become possible by fractal theory. However, whether the communication signals have fractal characteristics, and whether the fractal feature can be used to achieve accurate feature extraction of signals is still a problem worth exploring. This paper first took QPSK signal as an example, and used mathematical methods to prove that the communication modulation signals have fractal characteristics. Then, an improved fractal box dimension algorithm was used to extract and recognize five signals to verify the effectiveness of fractal theory based feature extraction. Simulation results illustrate that the recognition result can achieve 97.8% even under the SNR of 10dB environment. This provides a theoretical basis for the wide application of fractal theory in the field of signal identification.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123531980","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}

Focused on the problem above, a novel method in view of the effectiveness of reconstruction is proposed in this paper, which can reduce computational complexity with little performance degradation under the low input SNR. The central idea is that the determination factor (DF), which is defined by whether the desired signal can be estimated, is introduced as the criterion of the INCM reconstruction. Firstly, the Multiple Signal Classification (MUSIC) is used to exploit the relationship between the DF and the input SNR. Then whether the INCM is necessary to reconstruct is determined by the DF. Finally, the corresponding INCM is calculated. Theoretical analysis and simulations show that the proposed beamformer obtains better performance compared with the reconstruction-based beamformer and can balance the complexity and performance well.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116416160","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}
