| Abstract |
The topic of this paper is content-based retrieval of 3D
models that are represented as triangle meshes. An object
from some 3D geometry database can traditionally be
accessed using attached structural information such as
textual annotation. However, there are frequent
requirements for a content-based retrieval of various
multimedia contents. A content-based 3D model retrieval
system has been implemented and this system is
presented here. Models are retrieved by querying using
another 3D model where the shape description for the
query model is automatically created. The proposed
feature vector is invariant with respect to translation,
rotation and uniform scaling. |
