摘要

准确检测和表征脑电图信号的变化对临床评估神经系统状况至关重要。测试和评估了几种距离测量方法在脑电图中检测损伤相关变化的有效性。发现Itakura距离是表征脑电图变化的一种非常有效的手段,既可以信号损伤,也可以预测恢复。通过光谱距离测量和Kullback-Leibler信息的对比研究,进一步确立了Itakura距离测量的有效性。

Quantification of injury-related EEG signal changes using Itakura distance measure
Accurate detection and characterization of changes in the EEG signal is crucial for clinical assessment of the neurological system condition. Several distance measures are tested and evaluated for their effectiveness of detecting injury-related changes in EEG. Itakura distance is found to be a very efficient means to characterize changes in EEG for both signaling injury and predicting recovery. The efficiency of the Itakura distance measure is further established through a comparison study of spectral distance measure and Kullback-Leibler information.
