Mixed Electrocardiogram Human Identification Method Using Analysis Model and Appearance Model
摘要
Abstract
In order to improve the sensitivity of Electrocardiogram(ECG) identification to noise and changes of signal,and to prioritize heartbeat features,a hybrid ECG human identification method is proposed.Heartbeat and appearance properties are jointly analyzed in the proposed method,in which Fisher linear discriminant analysis method is used to obtain the main attributes from these properties and the heartbeat features are calculated in Fisher space.The feature in time domain is used to calculate ECG characteristics.After the heartbeat feature in time domain is deducted by a series of heartbeat,the morphological characteristics are obtained by standardizing and scaling ECG signals.By maximizing the rate between the between-class individual hash and in-class individual hash,the most discriminative features are selected.Experimental results show that the recognition accuracy of the proposed method in a large database of healthy individuals is 99.24%.When the body is in the case of heart disorders,the Equal Error Rate(EER) is only 0.76%.In a mixed state,EER is 1.31%.So the robustness is well verified.关键词
