As shown in the figure, non-rigid 3D objects are commonly seen in our surrounding. Therefore, how to efficiently and accurately compare non-rigid 3D shapes is of great significance in practice. However, the non-rigid 3D models database of SHREC’11 Track contains inadequate categories of non-rigid shapes, which are not diversified enough in both texture and topological structure. Many state-of-the-art non-rigid shape retrieval methods achieve an extremely high accuracy rate on this benchmark. It is thereby difficult to distinguish between good methods and demonstrate improvement in new proposed approaches. Therefore, we organize this track to promote the development of non-rigid 3D shape retrieval by expanding the original non-rigid 3D shapes of SHREC’11 in three directions: quantity, category and complexity.
The objective of this track is to evaluate the performance of 3D shape retrieval approaches on a large-scale database of non-rigid 3D watertight meshes generated by our group.
(Note that: Some of these models we recreated and modified with permission are originally from several publicly available databases: such as McGill database, TOSCA shapes, Princeton Shape Benchmark, etc.)
- The participants must register by sending a message to SHREC@pku.edu.cn. Early registration is encouraged, so that we get an impression of the number of participants at an early stage.
- The test database will be made available via this website. Participants should also test their methods on the database used in SHREC 2011 Non-rigid track and submit their results to get the password to access the new database.
- Participants will submit the dissimilarity matrix (also named as distance matrix) for the test database. Upto 5 matrixs per group may be submitted, resulting from different runs. Each run may be a different algorithm, or a different parameter setting. More information on the dissimilarity matrix file format
- The evaluations will be done automatically.
- The organization will release the evaluation scores of all the runs.
- The participants write a one page description of their method and the organizers will verify the submitted results.
- The track results are combined into a joint paper, published in the proceedings of the Eurographics Workshop on 3D Object Retrieval.
- The description of the tracks and their results are presented at the Eurographics Workshop on 3D Object Retrieval (May 2-3, 2015).
