Modeling virtual environments is a time consuming and expensive task that is becoming
increasingly popular for both professional and casual artists. The model density and …

We present a novel 3D shape descriptor that uses a set of panoramic views of a 3D object
which describe the position and orientation of the object's surface in 3D space. We obtain a …

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 …

The explosively increasing 3-D objects make their efficient retrieval technology highly
desired. Extensive research efforts have been dedicated to view-based 3-D object retrieval …

Large corpora of 3D models, such as Google 3D Warehouse, are now becoming available
on the web. It is possible to search these databases using a keyword search. This makes it …

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 …

Relevance feedback techniques are expected to play an important role in 3D search
engines, as they help to bridge the semantic gap between the user and the system. Indeed …

The estimation of 3D surface correspondence constitutes a fundamental problem in shape
matching and analysis applications. In the presence of non-rigid shape deformations, the …

In this study, we present a parallel approach to relevance feedback based on similarity field
modification that simultaneously considers all factors affecting the similarity field for 3D …

We have studied the problem of retrieval of arbitrary object instances from a large point
cloud data set. The context is autonomous robots operating for long periods of time, weeks …
