Heart sound classification based on scaled spectrogram and tensor decomposition
作者：
Highlights：
• First, the spectrograms of heart cycles are scaled for comparison.
• Second, tensor decomposition is utilized to the scaled spectrograms.
• Third, the intrinsic structure information of scaled spectrograms is extracted.
• Fourth, more useful physiological and pathological information is reserved.
• Fifth, the extracted features are more discriminative.
