The original algorith works by joining the wavelet transform values along local maxima for increasing window lengths. Ridge lines obatained in this manner are taken to correspond to peaks if they satisfy certain criteria (length of the ridge, SNR, etc.) In our extension, the width of the peak is obtained from finding the first maximum of the wavelet transform values along the ridge line.
Region estimation is performed iteratively. This is done to ensure that
regions containing overlapping events are correctly identified. At each pass regions which have no overlaps and regions which only overlap with regions having a lower peak SNR are fitted. After
this a successful fit, the
fit result is subtracted from the original signal and region detection is performed again, followed by fitting. This
process is
done continued until no more regions are detected or successfully fitted.
