The difference between using the traditional GMM and the online GMM to build an atlas. A test subject is clustered adaptively using two atlases generated by these two approaches. The average Fréchet distances both between the generated atlases and between the fiber bundles of the test subject are given. The size of the atlas is given in parenthesis. The baseline distance is calculated by running a single GMM with different random initializations to illustrate an approximate lower bound for the Fréchet distance. The difference between the results of traditional and online GMMs increases as the atlas size increases. This introduces a tradeoff between the reliability of the online GMM and the generalizability of the resulting atlas.
