Segmentation-based heart sound feature extraction combined with classifier models for a VSD diagnosis system ?
A diagnosis system is proposed for diagnosing a VSD. The diagnostic features [FG,FW F G , F W ] based on a novel method are extracted. A classification boundary method based on the SVM is proposed. Ellipse fitting is employed to build ellipse models for boundary curves. The performance is evaluated by clinical heart disease.
