Structural Shape Prototypes for the Automatic Classification of 3D Objects
Simone Marini, Michela Spagnuolo, Bianca Falcidieno · IEEE Computer Graphics and Applications · 2007
This technique for defining and constructing 3D shape prototypes improves automatic 3D content classification and search by summarizing key features of the members of a class, then classifying the query object into the class that the prototype most similar to the given query represents.
