Cardiac anomaly detection considering an additive noise and convolutional distortion model of heart sound recordings

作者:

Highlights:

• Heart sounds can be corrupted with additive noise and convolutional degradation (sensor effect).

• We mathematically analyze the effect of additive noise & convolutional distortion on heart sounds.

• We propose a fusion of linear and logarithmic features input to a CNN for disease classification.

• Achieved superior results compared to existing methods in presence of sensor/noise variability.
