Classification of Children's Heart Sounds With Noise Reduction Based on Variational Modal Decomposition

Classification of Children's Heart Sounds With Noise Reduction Based on Variational Modal Decomposition

PurposeChildren's heart sounds were denoised to improve the performance of the intelligent diagnosis.MethodsA combined noise reduction method based on variational modal decomposition (VMD) and wavelet soft threshold algorithm (WST) was proposed, and used to denoise 103 phonocardiogram samples....
