BOTERO SUAREZ, Claudia C.; TALAMONI FONOFF, Erich; BALLESTER, Gerson e RAMIREZ-FERNANDEZ, Francisco Javier. PREVENTION OF EPILEPTICAL CRISIS USING WAVELET TRANSFORM AND CROSS-CORRELATION. Rev. ing. univ. Medellin [online]. 2007, vol.6, n.11, pp.223-232. ISSN 1692-3324.
This paper describes the detection of a pre-crisis activity through the application of Cross-Correlation together with the Wavelet Transform. The Wavelet Transform is applied in the data reduction and pre-processing of signals. This feature extract technique provides the simplified signals to process by means of the Cross-Correlation technique. The analysis with a group of pre-crisis and inter-crisis data (including both induced acute crises and recurrent spontaneous crises), to determinate its sensitivity and its specificity (False Prediction Rate) has been done. The seizure occurrence period and the seizure prediction horizon are calculated additionally.
