Class Information
Number: 382/204
Name: Image analysis > Pattern recognition > Feature extraction > Local or regional features > Shape and form analysis > Topological properties (e.g., number of holes in a pattern, connectivity, etc.)
Description: Subject matter in which the features do not depend on measurements of dimensions or areas but are concerned instead with numbers or relationships of the different geometrical units (vertices, edges, faces, holes) involved.
