An Environment for Complex Behaviour Detection in Bio-potential Experiments

We propose BioS (Bio-potential Study) as a new virtual data anal-ysis and management environment.It was devised to cope with the physiologicalsignals, in order to manage di®erent data using advanced methods of analy-sis and to ¯nd a simple way to decode and interpret data. BioS has beenstructured as a °exible, modular, and portable environment. It includes sev-eral modules as data importing and loading, data visualization (1D, 2D, 3D),pre-processing (frequency and saturation ¯ltering, statistical analysis), spatio-temporal processing such as power spectrum, independent component analysis(ICA) in spatial and time domain, and nonlinear analysis for the extractionof the maximum Lyapunov exponent and d1(d-inifnite) using optimized al-gorithms. The environment provides a user-friendly Graphic User Interfacethat allows inexperienced users to perform complex analyses and to speed upexperimental data processing.
