Abstract: 3D-Polarized Light Imaging (3D-PLI) provides data that enables an exploration of brain fibers at very high resolution. However,the visualization poses several challenges. Beside the huge data set sizes, users have to visually perceive the pure amountof information which might be, among other aspects, inhibited for inner structures because of occlusion by outer layers ofthe brain. We propose a clustering of fiber directions by means of spherical harmonics using a level-of-detail structure bywhich the user can interactively choose a clustering degree according to the zoom level or details required. Furthermore, theclustering method can be used for the automatic grouping of similar spherical harmonics automatically into one representative.An optional overlay with a direct vector visualization of the 3D-PLI data provides a better anatomical context.
