This paper presents an online algorithm of separating lung sounds for computer-aided diagnosis. A lung sound consists of breath sounds, and possibly discontinuous sounds and continuous sounds due to pulmonary disorders. Repetitive breath and discontinuous sounds are linearly dependent.
The continuous sounds have sparse instantaneous frequency components. Our algorithm separates the linearly-dependent components and sparse components
from a auscultation sound in a sliding time window. We experimentally demonstrate the separation of continuous sounds from the other components. We also show the principal components of the breath and discontinuous sounds.
