Abstract
We propose a denoising and segmentation technique for the second heart sound (S2). To denoise, Matching
Pursuit (MP) was applied using a set of non-linear chirp signals
as atoms. We show that the proposed method can be used to
segment the phonocardiogram of the second heart sound into
its two clinically meaningful components: the aortic (A2) and
pulmonary (P2) components.
