Abstract

In this study we used similarity Techniques in the time-frequency plane for identification of sleep spindles (SS) and K complexes (KK). We used a Gabor transform on a representative sleep sample from 9 normal subjects. The results show a correlation between the expert / method, being possible to calculate sensitivity and specificity for the method. This result shows that the methodology lies on the same levels of time-frequency classical techniques. Here the advantage is that this technique has a wide band application. The test runned with K-complex is illustrative.
