Summary
- Plugin name : EOG Denoising Calibration
- Version : 1.0
- Author : Joao-Pedro Berti-Ligabo
- Company : Inria
- Short description : Algorithm implementation as suggested in Schlogl's article of 2007.
- Documentation template generation date : Apr 11 2018
Description
Press 'a' to set start point and 'u' to set end point, you can connect the Keyboard Stimulator for that
This box calculates a denoising matrix 'b' for removing the EOG effects on EEG. The principle is based on regression analysis (see article 'A fully automated correction method of EOG artifacts in EEG recordings' - Schlogl2007) where a matrix 'b' is estimated being: b = <'Nt N>-ยน<'N S> with N being the noise (EOG electrodes) and S the source (EEG electrodes). This box reads necessarily from a file where the subject does lots of blinks. User will set a starting and an ending point at this file then the program will calculates the b matrix after reading throughout the file.
