In this paper we propose an efficient method for S4 heart sound segmentation based on the Matching Pursuit algorithm and Gabor Dicitonaries. An evaluation of this algorithm, through the use of different cardiac cycle events for S4 heart sound signals, showed a high performance, achieving a detection rate of 100% with the use of Gabor dictionary.
