Investigating the Bag-of-Words Method for 3D Shape Retrieval

چکیده
This paper investigates the capabilities of the Bag-of-Words (BWs) method in the 3D shape retrieval field. The contributions of this paper are (1) the 3D shape retrieval task is categorized from different points of view: specific versus generic, partial-toglobal retrieval (PGR) versus global-to-global retrieval (GGR), and articulated versus nonarticulated (2) the spatial information, represented as concentric spheres, is integrated into the framework to improve the discriminative ability (3) the analysis of the experimental results on Purdue Engineering Benchmark (PEB) reveals that some properties of the BW approach make it perform better on the PGR task than the GGR task (4) the BW approach is evaluated on nonarticulated database PEB and articulated database McGill Shape Benchmark (MSB) and compared to other methods.

Spatially Enhanced Bags of Words for 3D Shape Retrieval
This paper presents a new method for 3D shape retrieval based on the bags-of-words model along with a weak spatial constraint. First, a two-pass sampling procedure is performed to extract the local shape descriptors, based on spin images, which are used to construct a shape dictionary. Second, the model is partitioned into different regions based on the positions of the words. Then each region ...
متن کاملSalient local 3D features for 3D shape retrieval
In this paper we describe a new formulation for the 3D salient local features based on the voxel grid inspired by the Scale Invariant Feature Transform (SIFT). We use it to identify the salient keypoints (invariant points) on a 3D voxelized model and calculate invariant 3D local feature descriptors at these keypoints. We then use the bag of words approach on the 3D local features to represent t...
متن کاملBag of Words and Local Spectral Descriptor for 3D Partial Shape Retrieval
This paper presents a 3D shape retrieval algorithm based on the Bag of Words (BoW) paradigm. For a given 3D shape, the proposed approach considers a set of feature points uniformly sampled on the surface and associated with local Fourier descriptors; this descriptor is computed in the neighborhood of each feature point by projecting the geometry onto the eigenvectors of the Laplace-Beltrami ope...
متن کاملThe bag of words approach on 3 D domain : retrieval , partial matching and categorization
In this paper the effectiveness of the Bag of Words framework is exploited for the 3D domain. Such approach provides a part-based representation by partitioning the objects into subparts and by characterizing each segment with different geometric descriptors. In this fashion one object is modeled as an histogram of subparts occurrences which becomes its signature. Therefore, such signature is f...
متن کاملVisual Vocabulary Signature for 3D Object Retrieval and Partial Matching
In this paper a novel object signature is proposed for 3D object retrieval and partial matching. A part-based representation is obtained by partitioning the objects into subparts and by characterizing each segment with different geometric descriptors. Therefore, a Bag of Words framework is introduced by clustering properly such descriptors in order to define the so called 3D visual vocabulary. ...
