In this paper, the temporal characteristic of spectral subbands of sleep EEG associated with different sleep stages is examined using a simple computational analysis technique based on the local minima and maxima. The average range of local min-max Rλ defined as the average differences between amplitudes of consecutive local minima and maxima is used as a temporal characteristic measure. From the...
In this study, a quantitative analysis method based on the local minima and maxima features is applied to the sleep EEG. The local minima (local maxima) is defined as a point whose amplitude is less (greater) than its neighbors. The average of local min-max intervals and the variance of local min-max intervals are used as temporal variability measures. From the computational results, it is observed...
