SHREC—08 entry: Local 2D visual features for CAD Model retrieval

A local shape feature has an advantage in dealing with deformable or articulated 3D models. We evaluate the performance of our local, 2D visual features and their integration method based on the bag-of-features approach using the SHREC’08 CAD Model Track. The evaluation showed that, it performed very well, winning the 2
^nd
place in the contest, although it lost to a method that employs supervised learning of classes in the benchmark dataset.
