A Comparison of Wavelet and Simplicity-Based Heart Sound and Murmur Segmentation Methods
… heart sounds and murmurs in digitized phonocardiogram audio files. Two separate segmentation techniques based on the discrete wavelet transform (DWT) and the simplicity transform are integrated into a MATLAB software system that is capable of automatically detecting and classifying …
