Towards human brain signal preprocessing and artifact rejection methods

چکیده
In the brain computer interface (BCI) research field, a neurological occurrence is the only source of control in any BCI system. Artifacts are contrary signals that can affect with neurological phenomena. These artifacts may lead to the source of control in BCI systems. Electromyography (EMG) and electrooculography (EOG) artifacts are physiological artifacts that are carefully processed in BCI systems. This paper describes the common EOG, EMG, and non-physiological artifacts associated with our experiment and the procedure for artifact rejection. During artifact rejection, we considered the presence of EMG and EOG artifacts in the brain signals. Results had shown the stability in brain signals after applying the artifact rejection such as, eye blink, eye movement, muscle movement, and bad channels.

Implementing a Smart Method to Eliminate Artifacts of Vital Signals
Background: Electroencephalography (EEG) has vital and significant applications in different medical fields and is used for the primary evaluation of neurological disorders. Hence, having easy access to suitable and useful signal is very important. Artifacts are undesirable confusions which are generally originated from inevitable human activities such as heartbeat, blinking of eyes and facial ...

Brain Computer Interface (BCI) is often directed at mapping, assisting, or repairing human cognitive or sensory-motor functions. Electroencephalogram (EEG) is a non-invasive method of acquisition brain electrical activities. Noises are impure the EEG recorded signal due to the physiologic and extra-physiologic artifacts. There are several techniques are intended to manipulate the EEG recorded s...
متن کاملImproved rejection of artifacts from EEG data using high-order statistics and independent component analysis
While it is now generally accepted that independent component analysis (ICA) is a good tool for isolating both artifacts and cognition-related processes in EEG data, there is little definite proof that data preprocessed using ICA is more effective than artifact rejection on raw channel data, especially when more subtle signal processing methods are used to detect artifacts. Here we applied five...
متن کاملA semi-simulated EEG/EOG dataset for the comparison of EOG artifact rejection techniques
Artifact rejection techniques are used to recover the brain signals underlying artifactual electroencephalographic (EEG) segments. Although over the last few years many different artifact rejection techniques have been proposed (http://dx.doi.org/10.1109/JSEN.2011.2115236[1], http://dx.doi.org/10.1016/j.clinph.2006.09.003[2], http://dx.doi.org/10.3390/e16126553[3]), none has been established as...
