Based on the capacity of WSDM system when sources are just two, we extend the WSDM system model and analyze the capacity under multiple sources condition. Computer simulations show that WSDM method can raise the bandwidth efficiency greatly. What's more, how to separate time-frequency mixed signals in WSDM system with multiple sources is a difficult problem. We propose optimal linear separation method by applying Rayleigh quotient scheme. The closed form expression of separating matrix is derived according to the proposed method. Computer simulations also verify the proposed method is feasible and perform better than independent component analysis (ICA) method.","PeriodicalId":159643,"journal":{"name":"2016 Sixth International Conference on Information Science and Technology (ICIST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133316132","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 SAO provides a superior image reconstruction quality at the cost of much higher computational complexity and it is more difficult to realize real-time coding when the image size is large, such as for high definition (HD) videos or ultra-HD videos. In this paper, we design the corresponding parallel algorithms for the SAO by exploiting GPU multi-core computing ability, including parallel computation of sample classification and statistics collection for each coding tree block (CTB), parallel calculation of the best offset values and minimum distortions for each class of edge offset (EO) and each band of band offset (BO), parallel processing of the SAO merging, and parallel implementation of SAO filtering. All the parallel algorithms are implemented on GPU programmed with CUDA language. Experimental results given in the paper show that, for HD video sequences, the parallel method can greatly improve the encoding efficiency of the SAO process with more than 22 times speedup while keeping the quality of reconstructed images unchanged, compared with the original serial algorithm implemented on CPU.","PeriodicalId":159643,"journal":{"name":"2016 Sixth International Conference on Information Science and Technology (ICIST)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124623684","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}

All distortions caused by the position change of camera are first modeled by different tilts images; then the feature points are localized by improved Accelerated-KAZE (AKAZE) algorithm, namely the feature points are detected in nonlinear space constructed by Fast Explicit Diffusion (FED) and variable conductance function, and the extracted feature points are described by improved SIFT descriptor; finally, Euclidean distance is used as similar metric to determine the correspondences and Random Sample Consensus (RANSAC) algorithm is employed to eliminate the false matches. In experiments of oblique images and UAV images, the number of feature points extracted by the proposed method is biggest, the effective correspondences are most and the correct matching ratio is highest among SIFT, ASIFT and our proposed algorithm. Thus, our proposed algorithm can be successfully used in oblique remote sensing image matching.","PeriodicalId":159643,"journal":{"name":"2016 Sixth International Conference on Information Science and Technology (ICIST)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122888827","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}

Two ultrasonic sensors are selected and separately assembled on a small turntable by the same distance to the origin along the coordinate axis X and Y directions. By designing tracking algorithms, the turntable can be controlled to locate the motion object, with which complicated equation problems can be solved. With a well-designed control instruction sequences, it is able to precisely control timing period and effectively reduce measure error caused by irregular delay from traditional commands.
