As shown in the figure, non-rigid 3D objects are commonly seen in our surroundings. However, previous efforts have been mainly devoted to the retrieval of rigid 3D models, and thus comparing non-rigid 3D shapes is still a challenging problem in content-based 3D object retrieval. Therefore, we organize this track to promote the development of non-rigid 3D shape retrieval.
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@nist.gov. 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 last year's SHREC 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 (April 10, 2011).
