Traditionally, waveform detection of each cardiac cycle in SCG was depended on the reference QRS complex in Electrocardiogram (ECG). The dominant wave in SCG, namely W complex, could be used as the feature wave for heartbeat segmentation. In this paper, matched-filtering approach was developed and evaluated for W complex detection in SCG without noise suppression stage. Firstly, the template of W complex was selected automatically by the triangle character in SCG and then was used as the coefficients of the finite impulse response (FIR), which greatly enhanced W complexes and attenuated other regions. Subsequently, W complex was detected using the triangle structure, and cardiac cycles and triangle structures were further analyzed for the reduction of false-positive and false-negative detections. The performance of the proposed algorithm was tested on 20 records (each record lasted 50 min) of the combined measurement of ECG, Breathing and Seism cardiograms Database (CEBSDB). The detection rate of 98.74%, the sensitivity of 99.33% and the positive prediction of 99.41 % was achieved on the CEBSDB, respectively. In conclusion, matched-filtering is reliable for the heartbeat segmentation of Seism cardiogram.","PeriodicalId":6592,"journal":{"name":"2015 7th International Conference on Intelligent Human-Machine Systems and Cybernetics","volume":"49 1","pages":"47-51"},"PeriodicalIF":0.0,"publicationDate":"2015-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83606375","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 mainly adopt three strategies to improve the original Seq SLAM algorithm: integrating Seq SLAM with odometry, optimizing sequence searching strategy and multi-scale sequence matching. The improved algorithm is evaluated using the KITTI dataset. The template library is created online using navigation information from the sliding-window visual-inertial odometer. When a place is recognized, the corresponding information is used as observation of the filter. The result shows the superiority of the proposed method in real-time place recognition. The optimized sequence searching strategy performs much better in minor deviations. Meanwhile, the advantages of longer sequence match (higher recall rate) and short sequence match (precise location) are combined together. At last, the navigation errors are greatly reduced by close-loop detection. The overall position error of odometer with Seq SLAM is 20.3m (0.55% of the trajectory), which is much smaller than the navigation errors of the single odometer (32.0m, 0.86%).","PeriodicalId":6592,"journal":{"name":"2015 7th International Conference on Intelligent Human-Machine Systems and Cybernetics","volume":"66 1","pages":"260-264"},"PeriodicalIF":0.0,"publicationDate":"2015-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81574247","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}
