a T-SNE embeddings of all four data sets using embeddings using the XZ density maps combined with morphometric statistics. b T-SNE embeddings using the XZ density maps combined with morphometric statistics. c T-SNE embeddings using XZ density maps combined with z-projection-based 2D persistence images. The ellipses are 95% coverage ellipses for each type, assuming Gaussian distribution and using robust estimates of location and covariance. They are not influenced by single outliers.
