A multiresolution complex Gabor dictionary with orthogonal matching pursuit produces consistent time-frequency features from multiple heart-sound segments that a vision transformer classifies into four systolic murmur types at 95.96% accuracy on the CirCor DigiScope dataset.

Classification of systolic murmurs in heart sounds using multiresolution complex Gabor dictionary and vision transformer
A multiresolution complex Gabor dictionary with orthogonal matching pursuit produces consistent time-frequency features from multiple heart-sound segments that a vision transformer classifies into four systolic murmur types at 95.96% accuracy on the CirCor DigiScope dataset.
