Automatic pediatric congenital heart disease classification based on heart sound signal

作者:

Highlights:

• A database of heart sounds in CHD is established using electronic stethoscopes and is proposed to be made publicly available online.

• We propose a segments-based segmentation algorithm for cardiac cycle identification of heart sound signals.

• Effective time and frequency domain features from different cardiac stages are designed for classifier training and testing.

• We establish a Random Forest and Adaboost based majority voting classifier for pediatric CHD classification.

• Through extensive experiments and comparisons, the proposed algorithms are verified to be competitive.
