Heart Sounds Classification using Feature Extraction of Phonocardiography Signal
The Phonocardiogram (PCG) signals contain very useful information about the condition of the heart. By analyzing these signals, early detection and diagnosis of heart diseases can be done. It is also very useful in the case of infants, where ECG recording and other techniques are difficult to implement. In this paper, a classification method is proposed to classify normal and abnormal heart sou...
متن کاملA Novel Feature Extraction Method for Heart Sounds Classification
The experimental results showed that the proposed method efficiently classifies heart sounds. Heart sound analysis is a b asic method for heart examination, w hich m ay s uggest t he pr esence of a c ardiac pa thology a nd a lso provide diagnostic information. In this study, a novel feature extraction method based on Independent Component Analysis is applied to classify nine different heart sou...
متن کاملDetermining the effective features in classification of heart sounds using trained intelligent network and genetic algorithm
Heart diseases are among the most important causes of mortality in the world, especially in industrial countries. Using heart sounds and the features extracted from them are among the non-aggressive diagnosis and prognosis methods for heart diseases. In this study, the time-scale, Cepstral, frequency, temporal and turbulence features are saved and extracted from the heart sounds, and then they ...
متن کاملFeature extraction techniques for ultrasonic signal classification
In this paper, we present two feature extraction techniques for the classification of ultrasonic NDE signals acquired from weld inspection regions of boiling water reactor piping of nuclear power plants. The classification system consists of a pre-processing block that extracts features from the incoming patterns, and of an artificial neural network that assigns the computed features to a parti...
متن کاملevaluation of abnormal heart sounds using phonocardiography and comparing them with echocardiographic findings in dog
background: one of the most important heart diseases in dogs is valvular insufficiency, which can be evaluated by diagnosis ways such as phonocardiography, echocardiography, etc. objective: the purpose of the current study was to evaluate of valvular insufficiencies with phonocardiography and echocardiography and using phonocardiography technique in detection of cardiac valvular disease in prac...
