@article{(Open Science Index):https://publications.waset.org/pdf/2170, title = {An Automatic Sleep Spindle Detector based on WT, STFT and WMSD}, author = {J. Costa and M. Ortigueira and A. Batista and T. Paiva}, country = {}, institution = {}, abstract = {Sleep spindles are the most interesting hallmark of stage 2 sleep EEG. Their accurate identification in a polysomnographic signal is essential for sleep professionals to help them mark Stage 2 sleep. Sleep Spindles are also promising objective indicators for neurodegenerative disorders. Visual spindle scoring however is a tedious workload. In this paper three different approaches are used for the automatic detection of sleep spindles: Short Time Fourier Transform, Wavelet Transform and Wave Morphology for Spindle Detection. In order to improve the results, a combination of the three detectors is presented and comparison with human expert scorers is performed. The best performance is obtained with a combination of the three algorithms which resulted in a sensitivity and specificity of 94% when compared to human expert scorers.}, journal = {International Journal of Biomedical and Biological Engineering}, volume = {6}, number = {8}, year = {2012}, pages = {397 - 400}, ee = {https://publications.waset.org/pdf/2170}, url = {https://publications.waset.org/vol/68}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 68, 2012}, }
