Denoising and segmentation of the second heart sound using matching pursuit [PDF]
, 2012 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

Automatic segmentation of heart sound signals using hidden markov models [PDF]
, 2005 The monitoring of respiration rates using impedance plethysmography is often confused by cardiac activity. This paper proposes using the phonocardiogram as an alternative, since the process of respiration affects heart sounds. As part of this research, a
