Developed data pre-processing programs of heart sound samples

Applied regression de-trending and wavelet de-noising algorithms to heart-sound samples. Eliminated 80% trend items and 87% noises on average. Processed sound data is converted to image data using Fast Fourier Transformation. Time against frequency image data is then fed into a Convolutional Neural Network for the identification of congenital heart disease.
