View-based 3-D object retrieval and recognition has become popular in practice, eg, in
computer aided design. It is difficult to precisely estimate the distance between two objects …

In view-based 3-D object retrieval, each object is described by a set of views. Group
matching thus plays an important role. Previous research efforts have shown the …

In view-based 3D object retrieval and recognition, each object is described by multiple
views. A central problem is how to estimate the distance between two objects. Most …

The success of object recognition and retrieval is largely determined by data representation.
A good feature descriptor can detect the high-level abstraction of objects, which contains …

To improve the retrieval performance on a classified 3D model database, we propose a 3D
model retrieval algorithm based on a hybrid 3D shape descriptor ZFDR and a class-based …

The effectiveness of 3D model recognition generally depends on the feature representations
and classification methods. Previous algorithms have not shown good capacities to detect …

Feature engineering plays an important role in object understanding. Expressive
discriminative features can guarantee the success of object understanding tasks. With …

3D object retrieval has attracted extensive research efforts and become an important task in
recent years. It is noted that how to measure the relevance between 3D objects is still a …

View-based 3D model retrieval uses a set of views to represent each object. Discovering the
complex relationship between multiple views remains challenging in 3D object retrieval …

In this paper, we present a new approach for generic 3D shape retrieval based on a mesh
partitioning scheme. Our method combines a mesh global description and mesh partition …
