•  Intracranial aneurysms (IAs) are pathological deformations of brain arteries that expose the patient to an increased risk of subarachnoid hemorrhage and that are difficult to treat in general!

•  3D-shape descriptors are used to quantify and compare characteristics encoded in the shape of a 3D object!

•  Zernike Moment Invariants (ZMI) are derived from an orthonormal basis of radially modulated spherical harmonics, the so called Zernike polynomials:!
