Speech feature extraction constitutes the front end module of any speech decoder: it plays an essential role and has a strong impact on the recognition performance. The research community is aggressively searching for more powerful solutions which combine the existing feature extraction methods for a better and more reliable information capture from the analog speech signal. In this research work, we propose new approaches to combining phoneme recognizers' output in order to provide better recognition performance and improved robustness with respect to noise and channel distortions. Machine learning tools such as the Naive Bayes Classifier, Decision Trees, and Support Vector Machines have been used in the combination of hypotheses. Experiments under different SNR levels have proven that our proposed approach outperforms the two most common feature extraction techniques, namely Mel Frequency Cepstral Coefficients (MFCC) and Perceptual Linear Prediction(PLP) with Cepstral Mean Subtraction (CMS) and RASTA respectively, for channel normalization.","PeriodicalId":126072,"journal":{"name":"2009 3rd International Conference on Signals, Circuits and Systems (SCS)","volume":"243 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115833229","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 increased volume of satellite images has reinforced the need for automatic image registration methods. In this paper, two new feature-based approaches to automated image-to-image registration are presented. The characteristic of the first approach is that it combines an invariant moment shape descriptor with improved chain-code matching to establish correspondences between the potentially matched regions detected from the two images. This method works well for image pairs in which the contour information is well preserved, such as the optical images from Landsat and Spot satellites. For the registration of the optical images with synthetic aperture radar (SAR) images, we propose another method based on the wavelet transform, this second method uses spectral information of the images and their local wavelet transform modulus maxima to extract a set of control points. The experimental result demonstrates the robustness, efficiency and accuracy of the two algorithms.","PeriodicalId":126072,"journal":{"name":"2009 3rd International Conference on Signals, Circuits and Systems (SCS)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132044470","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 acquisition system is remotely connected to the company yacht database, so that it is automatically configured to handle the production test of a specific model among hundreds of possible different yachts, each one with its specific sensor and subsystem configuration. It consists of a hardware section (a PC provided with several converters that make the data available on a USB bus) and a software package that collects the data, decodes the digital protocols (NMEA 0183, CAN J1939, TCP/IP, etc.) and provides a common interface for visualization, data storage and test management. A wireless 2-axis inclinometer, not available on board, has also been designed, realized and integrated as a further sensor to be acquired. The acquisition system has extensively been utilized in the characterization of many different models and has proved a significant improvement in the yacht production tests, making this phase rigorous, documented, shorter and thus much cheaper and efficient than before.","PeriodicalId":126072,"journal":{"name":"2009 3rd International Conference on Signals, Circuits and Systems (SCS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114350573","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}
