Identification of fundamental heart sounds from PCG using blanket fractal dimension

Paper introduces a new approach for S1 versus S2 heart sound classification. The blanket fractal dimension is used for the first time for recognizing a heart sound candidate as S1 or S2 without the use of synchronous electrocardiogram. Even though the systole and diastole duration is not calculated for further improvement of the results, the obtained accuracy is more than 80% without any prior knowledge of patients' health issues.
