## Subtopics

- Hole (topology) [r]:
*Add brief definition or description* - Euler characteristic [r]: In a polyhedron, a number calculated as the number of vertices minus the number of edges plus the number of faces; it is always equal to 2 for convex polyhedra.
^{[e]}

- Remeshing [r]: A change in number, shape, size or arrangement of the polygons forming a surface mesh.
^{[e]} - Non-Uniform Rational B-Splines [r]:
*Add brief definition or description* - Genus (topology) [r]: A number derived from the Euler characteristic of a surface, equal to the number of "holes" or "handles"; a Betti number.
^{[e]} - Closure (topology) [r]: A set together with all its limit points.
^{[e]} - Topology (geography) [r]:
*Add brief definition or description* - Volumetric imaging [r]:
*Add brief definition or description* - Imaging artifact [r]: A property of an image that is mainly reflective of the imaging process, rather than the object being imaged, e.g. a susceptibility artifact in Magnetic Resonance Imaging.
^{[e]} - Image segmentation [r]: The (usually algorithmic) decomposition of an image on the basis of some of its properties, e.g. edges or intensity gradients.
^{[e]} - Marching cubes [r]: In computer graphics, an algorithm for constructing a 3D surface mesh from scalar 3D data, e.g. as obtained from neuroimaging.
^{[e]} - Brain morphometry [r]: The quantitative study of structures in the brain, their differences between individuals, correlations with brain function, and changes of these characteristics over time.
^{[e]} - Morse theory [r]:
