Wavelet based watermarked normal and abnormal heart sound identification using spectrogram analysis

Abstract: The present work proposes a computer-aided normal and abnormal heart sound identification based on Discrete Wavelet Transform (DWT), it being useful for tele-diagnosis of heart diseases. Due to the presence of Cumulative Frequency components in the spectrogram, DWT is applied on the spectrogram up to n level to extract the features from the individual approximation components. One dimensional feature vector is obtained by evaluating the Row Mean of the approximation components of these spectrograms. For this p… Show more

“…Imaging techniques are mainly carried out to analyze various physical properties, such as the surface area, number of blood cells, properties of tissue, and the behavior of any organs (Eils & Athale, ). Researchers are interested in the analysis of different types of biomedical images and applications collected from numerous modalities as described in Araki et al, (), Chakraborty, Samanta, Biswas, Dey, and Chaudhuri (), Dey, Roy, Pal, and Das (), Dey, Roy, Das, Das, and Chaudhuri (), Dey, Das, Roy, Das, and Chaudhuri (), Dey, Das, and Chaudhuri (), Dey et al (), Hore et al (). The microscope is one of the main medical image acquisition devices, which has several types including Light‐, Electron‐, Fluorescence‐, and Stimulated Emission Depletion‐microscopy (Pepperkok & Ellenberg, ).…”

“…The documents come from a patient's electronic medical record and medical problems. The huge amount of publications in medicine [2][3][4][5][6] signifies a massive supply of knowledge, which can efficiently be accessed by developing automated information extraction tools. However, using the strength of computer technology helps people to extract knowledge from large amounts of semi-structured or unstructured texts [7].…”
