GLOBAL JOURNAL OF ENGINEERING SCIENCE AND RESEARCHES A COMPARISON STUDY FOR 3D OBJECT RESEARCH BY THE CONTENT BASED METHODS

ABSTRACT In this paper, the method that we propose is a part of indexing and retrieval of 3D models in large databases, in this context we are particularly interested in a comparative study between the 2D/3D approach methods, Each method at its own technical to characterize the 3D object by a set of different images automatically extracted of the 3D model, this study concerning the views-based approach and the level cuts approach. To index these images we will use a 2D descriptor to extract the feature vectors of each model set. We calculate the similarity measuring using the Hausdorff distance. To retrieve the similar 3D objects of robustly manner we test the methods in the NTU database that we finally permit to find the efficient method that representing the 3D object
