A 3-dimensional EEG topography based on the polygon technique
보간 알고리즘 비교와 폴리곤 테크닉에 기초한 3차원 EEG 맵핑
Abstract
To obtain 3-D topography of EEG records, we propose a new method based on the polygon mapping technique. The method has the low complexity to calculate the interpolation of the EEG records on the scalp and maintains the high resolution topography because the polygon technique performs the interpolation at the only vertexes of each polygon. We implemented the topographic system with 3D barycentric, 3D polynomial and spherical spline algorithms in a personal computer.
