| Abstract: | In this paper, the effect of three time-frequency representations on a novel correlation algorithm is studied. By representing the signal in time-frequency domain, a redudant representation of the signal is obtained, and the algorithm presented here relies on such redundacies to extrapolate the significant features. The developed scheme has been applied to heart sound analysis using real recordings from patients, where the opening snap (OS) is distinguished from the third heart sound (S3). The results are compared for the three time-frequency transforms, and very encouraging results have been obtained with S-transform. | ||
