An Ellipsoidal 3D Shape Representation and Wavelet Transform Feature Descriptor for 3D Shape Retrieval
For the year of past most three-dimensional objects are represented and mapped with spherical function. Since the mapping preserves important criteria such as geometrical information of a 3D object, the representation of a 3D shape in a suitable way is an important matter for 3D object retrieval. In many circumstances, spherical surface fitting to a 3D shape does not approximate very well, beca...
متن کاملUsing Ellipsoidal Harmonics for 3D Shape Representation and Retrieval
A novel approach for 3D Shape description, applicable for search and retrieval applications, based on the theory of Ellipsoidal Harmonics is presented in this paper. The Ellipsoidal Harmonics are appropriately adopted in order to describe volumetric represented 3D objects. The experimental results, performed in a complete 3D object database, prove the efficiency of the proposed approach.
متن کامل3D Object Retrieval Using Compact Shape Descriptor
The need for effective and efficient 3D object retrieval approaches is emerging in a broad range of applications in science and engineering. With the increasing understanding of shape geometry and topology in the context of shape similarity, workable solutions for 3D object retrieval are being produced. In this paper, we present a novel technique for 3D Object Retrieval. The key idea of the pro...
متن کاملAn Ellipsoid Shape Approximation Approach for 3d Shape Representation
Shape representation plays an important role to preserve shape geometry information of any object. The majority of existing shape representation methods used sphere to approximate 3D object. Sphere is divergence in nature and hence the mapping between sphere and object is noncompact and the resultant shape representation becomes less informative. In this paper, we propose a shape representation...
متن کاملShape-based 3d Model Retrieval System Based on Elevation Descriptor
Recently, with the construction of digital libraries, the management of the large multimedia databases becomes an important issue. Unfortunately, traditional keyword searching techniques are not always effective for multimedia information. Thus, computer science has make incredible progress in retrieval of multimedia data based on image content. However, most of retrieval systems are focus on t...
