An Application of a Neuronal Method Used to Remove Artefacts
Dan-Marius Dobrea, Monica Claudia Dobrea · 2007
The aim of this paper is to present an adaptive artifact removing technique – used in a bioinstrumental system –, able to eliminate or reduce the artifacts from the respiratory signal. The noncontact bio-instrumental complex is used to determine the fatigued state of a person who is caring out activity under the stress conditions. The final aim is to discriminate/recognize the fatigue state, based on the information that is confined, simultaneously, in the respiratory signal, hand tremor and body torso movements. One of the major problems of this system is generated by the artifacts that disturb the signals. In this particular case, that will be present in this paper, the respiratory signal is one affected by the artifacts. In order to eliminate the respiratory artifacts two methods were used and the results are presented in this paper. A comparison between the methods is also presented.
