Study of Tunnel Morphin the Similarity Analysis of Time Series Bio-signal Data

One similarity measurement strategy for bio-signal waveform is presented in this paper. A tunnel morph is introduced to describe the waveform. It measures the waveform not only by a value, but considers the curve feature of waveforms. Then a set of integrity definitions are presented in the paper. It contains tunnel construction, tunnel morph width, edge detection, class judgment. A case study on AECG (Ambulatory Electrocardiogram) is also presented to give a proof for the similarity measurement strategy. Through experiments, each type of dataset could be integrated into a tunnel, then, every unknown data whether belongs to this tunnel can be evaluated. Data used in the paper is from MIT/BIH.
