A system of epilepsy seizure detection in real life conditions and based on inertial sensors is presented in this paper with a focus on the signal processing to recognize seizure moves. This system is based on several models of signals, one corresponding to general movements, and two others describing seizures moves. The detection algorithm evaluates for a given time window which model fits the best with the observed signals and trigger an alarm if this model is a seizure model. The signal processing algorithm is based on hidden Markov models.
本文提出了一种基于惯性传感器的癫痫发作检测系统,该系统适用于现实生活环境,重点在于通过信号处理来识别癫痫发作动作。该系统基于多种信号模型,一种对应一般动作,另外两种描述癫痫发作动作。检测算法会在给定的时间窗口内评估哪种模型与观测信号最匹配,如果该模型是癫痫发作模型,则触发警报。信号处理算法基于隐马尔可夫模型。
