🤖 AI Summary
This study addresses the inefficiency and limited scalability of manual artifact component identification in traditional electroencephalography (EEG) research following independent component analysis (ICA). To overcome this bottleneck, the work introduces computer vision techniques into the automatic labeling of ICA components for the first time, developing an end-to-end automated system compatible with both EEGLAB and ICLabel. The proposed method enables efficient detection and removal of non-neural components, substantially reducing reliance on expert annotation. It achieves a classification accuracy of 89.45% while accelerating processing speed by a factor of 7,200 compared to manual approaches, thereby facilitating large-scale and near real-time EEG analysis.
📝 Abstract
The electroencephalogram (EEG) is a valuable and widely applied tool for investigating brain disorders and behavioral changes. It offers a minimally restrictive and non-invasive method. However, challenges in using EEG for cognitive development studies include temporal resolution, signal source localization, and EEG artifacts. Careful consideration of these factors is essential for informed application of EEG technology. Independent component analysis (ICA) effectively isolates source generator processes from signals recorded by multiple, adjacent EEG scalp electrodes. Although ICA decomposition requires manual inspection, selection, and interpretation of independent components (ICs), this process is time consuming and demands expertise. Automated IC classification can achieve sufficient accuracy, expediting large scale EEG research and enabling near real time applications in conjunction with brain activity rejection tasks, which are crucial for medical specialists. This study introduces an automated computer vision based ICA rejection labeling tool compatible with widely used software interfaces like ICLabel and EEGLab. By automating the manual task, the proposed system reduces processing time by 7200 fold and achieves an accuracy of 89.45%.
