Research on Identiifcation System Based on ECG Signal
摘要
Abstract
Objective To design a set of identiifcation system based on ECG signal and to carry out algorithm design for the ECG signal so as to realize the function of identity recognition.Methods Firstly, ECG data was collected partly from MIT database of the ECG data and partly from a portable ECG acquisition device. Then the features of ECG signals were extracted and the highest point of each R wave was located. We extracted 80 points before the highest point of the R wave and 170 points after the highest point. Finally, the principal component analysis (PCA) was used to reduce the dimension of data in matrix laboratory (MATLAB). The lineal discriminant analysis (LDA) was adopted to design a categorizer, which was also tested.Results The experimental result indicated that the use of portable ECG acquisition equipment could collect ECG data in real time. The data after classiifcation was unique and the correct classiifcation rate was above 90%.Conclusion This system has high innovation at the level of technology and application, which could provide certain guarantee for the security of the society, and has certain application value.关键词
