Abstract
A computer-based method for detecting features in a digitally sampled biological (bio) signal includes the steps of applying a wavelet transform to the bio signal to generate a list of wavelet transform coefficients, ranking the coefficients according to value or frequency, and removing at least one low value or low frequency coefficient. The method further includes the steps of performing an inverse wavelet transform using the remaining coefficients to generate a reconstructed signal, and detecting feature locations using the reconstructed signal.
