3D Object Retrieval using an Efficient and Compact Hybrid Shape Descriptor
نویسندگان
چکیده
We present a novel 3D object retrieval method that relies upon a hybrid descriptor which is composed of 2D features based on depth buffers and 3D features based on spherical harmonics. To compensate for rotation, two alignment methods, namely CPCA and NPCA, are used while compactness is supported via scalar feature quantization to a set of values that is further compressed using Huffman coding. The superior performance of the proposed retrieval methodology is demonstrated through an extensive comparison against state-of-the-art methods on standard datasets.

متن کامل3D Models Recognition in Fourier Domain Using Compression of the Spherical Mesh up to the Models Surface
Representing 3D models in diverse fields have automatically paved the way of storing, indexing, classifying, and retrieving 3D objects. Classification and retrieval of 3D models demand that the 3D models represent in a way to capture the local and global shape specifications of the object. This requires establishing a 3D descriptor or signature that summarizes the pivotal shape properties of th...
متن کاملSymmetry and Fourier Descriptor: A Hybrid Feature For NURBS based B-Rep Models Retrieval
As the number of models in 3D databases grows, an efficient 3D models indexing mechanism and a similarity measure to ease model retrieval are necessary. In this paper, we present a query-by-model framework for NURBS based B-Rep models retrieval that combines partial symmetry of the object and the Fourier shape descriptor of canonical 2D projections of the 3D models. In fact, most objects are co...
متن کاملContent-based 3D model retrieval considering the user’s relevance feedback
This dissertation deals with the problem of enabling precise and real-time retrieval of generic 3D models. We focus on three subproblems, namely, rotation normalization, discriminative shape representations and relevance feedback-based retrieval. Considering the first problem, we develop a rotation normalization method that computes the object’s principal axes using the orientation of the objec...
