Movie examples: Geodesic mean on manifolds
The evaluation of geodesic mean on manifold (S1 and S2) with moving data points is illustrated in the following movies- Geodesic mean on S1
- Geodesic mean on S2, three data points moving along the equator
- Geodesic mean on S2, three data points moving along directions 120 degree to each other
- Geodesic mean on S2, four data points moving along directions 90 degree to each other
- Geodesic mean on S2, six data points
Useful Softwares
- Mondrian is an interactive Statistical Data Visualization tool. Dr. Antony Unwin recently introduced this great and free software in the shapestat meeting of MIDAG.
- Inkscape is a vector drawing tool that can be used to generate mathematical graphics and diagrams. It can be combined with textext, which allows you to type scientific formulars via Latex code.
