In this paper, we present a new approach for generic 3D shape retrieval based on a mesh partitioning scheme.  ...  We show that mesh partitions are representative and therefore it helps to improve the effectiveness in retrieval tasks.  ...  Another important aspect is the flexibility of the adaptive clustering algorithm with respect to the obtained number of clusters.  ...

It then computes the distance between initial centroids with the remaining data objects and groups the data objects into the cluster centroids with minimum distance.  ...  The performance of the proposed algorithm is well-compared with the accuracy of the traditional k-means clustering in terms of building meaningful clusters and to prove its real time usefulness.  ...  The clustering algorithm proposed in this chapter also takes the advantage of labeled classifier for correctly clustering the data objects based on the classes so as to improve the accuracy of clustering  ...
