3D model search and retrieval based on the 3D Radon transform

This paper describes a novel method for 3D model content-based search and retrieval based on the 3D radon transform and a querying-by-3D-model approach. Descriptors are extracted using the 3D radon transform and applying a number of functionals on the transform´s coefficients. Similarity measures are then created for the extracted descriptors and introduced into a 3D model-matching algorithm. This results in a very fast and accurate matching method. Experimental results are presented evaluating the performance of the proposed method in terms of precision versus recall diagrams.
