Threshold choice for automatic spindle detection

In this paper five choices are presented to determine the threshold for sleep spindle automatic detection. The proposed methods are based on performance measures. The different threshold values are compared using a Wave Morphology for Spindle Detection algorithm. For the presented algorithm, sensitivity ranges from 47.9% to 94.7%, while specificity ranges inversely from 98.7% to 89.0% for the threshold values used; the maximum accuracy reached is 96.6%.
