The four time-delay-difference values of each array can be estimated by the methods of generalized cross-correlation. And then, the azimuth angle can be calculated with the special structure of the array. The distance between the target and the center of each array can be estimated by the four time-delay-difference values in theory, however, the satisfactory estimating precision of the distance need high estimating accuracy of time delay, and this is very difficult. Therefore, the acceptable position parameter of the target can be gained by the multi- angles of multi-arrays. Double five-elements-cross arrays are placed in one area with 500*500 meters in the simulation, and the estimation error of the azimuth angle is less than 0.4 degree, and the coordinate error is less than 10 meters. The results of the simulation show the algorithm is effective and has high performance.","PeriodicalId":321908,"journal":{"name":"2012 International Conference on Computational Problem-Solving (ICCP)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123804832","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 bandpass filter is realized by two half-wavelength resonators which are coupled at their ends. Thus, it adds extra transmission zeros to the filter, which can effectively reject strong interference in the stopband. By using the symmetric and skew-symmetric feed structures, two transmissions zeros are created to the filter response, and the filter presents good out-of-band performance. Through theoretically analyses in combination with electromagnetic simulation, a balun-filter with extra transmission zeros is realized. The century frequency of the designed filter is 2.4GHz with 4% bandwidth, which is widely used in Wireless Personal Area Network (WPAN). The experimental measurement agrees well with the simulation result.","PeriodicalId":321908,"journal":{"name":"2012 International Conference on Computational Problem-Solving (ICCP)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115063893","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}

This paper proposes a novel lane departure algorithm for detecting lane markers in images acquired from a forward-looking vehicle-mounted camera. The interested targets of the algorithm are always the nearest two lanes to the automobile, and it can detect the left and right lane separately, which would generate the departure warning more precisely. As the main idea is two sure a straight line, the endpoints of segment lanes of the last image can be used as prior information to estimate lanes in the following one. It's a real-time algorithm for lane detection and tracking, which is also simple to implement. The experimental results on local streets and highways show that the suggested algorithm is very reliable and robust.","PeriodicalId":321908,"journal":{"name":"2012 International Conference on Computational Problem-Solving (ICCP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126323627","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 digital imaging devices generate huge amount of data, which makes it an urgent task to develop fast, accurate and automatic data processing technologies for the biomedical research. In this paper, we propose a novel method for counting the number of subcellular structures labeled by GFP. First, the original GFP image is segmented into foreground and background by the bi-modal Gaussian distribution modeling. Then, the gray-scale reconstructive opening operation is applied to find the local maxima of the image. Finally, the number of the subcellular structures is counted by the connected component analysis on the local maxima. The proposed method is compared with other existing methods and the experimental results demonstrate that our approach is promising.","PeriodicalId":321908,"journal":{"name":"2012 International Conference on Computational Problem-Solving (ICCP)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132262490","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}
