Discrete wavelet transform offers an effective solution for denoising nonstationary signals such as EEG due to its shrinkage property. In this paper, we explored the application of wavelet denoising method to EEG signals acquired during different sleep stages classified according to the RK rules, with the objective to identify suitable thresholding rules and threshold values. Preliminary results showed that the combination of soft thresholding rule applied to the Detailed wavelet coefficients with the Universal threshold value produced better performance measures such as a smaller Minimum Squared Error (MSE) and a larger signal-to-Noise Ratio (SNR). Similarly improved results were obtained for Stage 1, Stage 2, Stage 3, Stage 4 and REM stage EEG signals using this combination. Such thresholding rule and values are equally well applicable to denoising EEG epochs acquired from deep sleep stages.","PeriodicalId":432662,"journal":{"name":"CONIELECOMP 2011, 21st International Conference on Electrical Communications and Computers","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114306265","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}

Almost all of the VSLAM approaches use points 2D like features of the robot's environment for estimate his pose and the structure of his environment. We propose a new approach to get points 3D (i.e. feature's position and orientation with respect to the current robot's position are known) this approach is based in a monocular 3D reconstruction scheme; with this information we can improve the results in classical SLAM EKF method. Experiments had made in a structured environment, we implemented them for two cases, though; the first one was implemented without odometry and second one was carried out with partial odometry information; that means we included robot's orientation in EKF algorithm. This information had gotten with an IMU (Inertial Measurement Unit), which we installed in the robot. Finally, we want to point out that all the components used into the robotics' platform are low cost.","PeriodicalId":432662,"journal":{"name":"CONIELECOMP 2011, 21st International Conference on Electrical Communications and Computers","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115380287","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}
