Levenburg-marquardt Neural Wavelets Multilayer perceptrons Feature extraction Acoustic signal processing Cardiology Network Link to publisher's homepage at http://ieeexplore.ieee.org A heart sound feature extraction and classification method has been developed. It used the discrete wavelet decomposition and reconstruction to produce the envelopes of details of the signals for further extracting the features. Some statistical variables were extracted from the processed signals and used as the features for the heart sounds classification. A Multilayer Perceptron Neural Network has been used for classification of heart sounds. The performance of the proposed method has been evaluated using 250 cardiac periods from heart sound simulator. The proposed technique produced high classification rate of 92% correct classification. 2009-11-19T10:26:02Z 2009-11-19T10:26:02Z 2008 Working Paper p.177-180 http://ieeexplore.ieee.org/xpls/abs_all.jsp?=&arnumber=4723403 http://hdl.handle.net/123456789/7345 en 5th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE 2008) Institute of Electrical and Electronics Engineering (IEEE) |
