SHREC'09 track: querying with partial models

Data provided by  National Institute of Standards and Technology

There are two objectives of this shape retrieval contest:

a) To evaluate partial similarity between query and target objects and retrieve complete 3D models that are relevant to a partial query object.

b) To retrieve 3D models those are relevant to a query depth map. This task corresponds to a real life scenario where the query is a 3D range scan of an object acquired from an arbitrary view direction. The algorithm should retrieve the relevant 3D objects from a database.

SHREC'09 Track: Generic Shape Retrieval

Data provided by  National Institute of Standards and Technology

The objectives of this shape retrieval contest are to evaluate the performance of 3D shape retrieval approaches on a new generic 3D shape benchmark.

Task description: In response to a given set of queries, the task is to evaluate similarity scores with the target models and return an ordered ranked list along with the similarity scores for each query.

NIST Atomic Reference Data for Electronic Structure Calculations - SRD 141

Data provided by  National Institute of Standards and Technology

Atomic Reference Data for Electronic Structure Calculations contains total energies, partial energies and orbital eigenvalues for the atoms hydrogen through uranium, as computed in several standard variants of density-functional theory, both non-relativistic and relativistic. This data has been calculated to micro-Hartree accuracy to provide a benchmark for electronic structure calculations.

NIST Observed Interstellar Molecular Microwave Transitions Database - SRD 116

Data provided by  National Institute of Standards and Technology

This database contains critically evaluated transition frequencies for the molecular transitions detected in interstellar and circumstellar clouds reported in the literature through mid-2008. The tabulated transition frequencies are recommended for reference in future astronomical observations in the centimeter and millimeter wavelength regions. The transition frequencies have been selected through a critical examination and analysis of the laboratory spectral data obtained from the literature.

SHREC'10 Track: Non-rigid 3D Shape Retrieval

Data provided by  National Institute of Standards and Technology

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 the subset of a publicly available non-rigid 3D models database----McGill Articulated Shape Benchmark database.

SHREC'10 track: Range scan retrieval

Data provided by  National Institute of Standards and Technology

The objective of this shape retrieval contest is to retrieve 3D models those are relevant to a query range scan. This task corresponds to a real life scenario where the query is a 3D range scan of an object acquired from an arbitrary view direction. The algorithm should retrieve the relevant 3D objects from a database.

Task description: In response to a given set of queries, the task is to evaluate similarity scores with the target models and return an ordered ranked list along with the similarity scores for each query. The set of query consists of range images.

A Benchmark for Automatic Best View Selection of 3D Objects

Data provided by  National Institute of Standards and Technology

BEST VIEW SELECTION corresponds to the task of automatically selecting the most representative view of a 3D model.

This benchmark aims to provide tools to evaluate automatic best view selection algorithms. It consists of the preferred viewpoints of 68 models selected by 26 human subjects, and a code to calculate "View selection error". The subjective viewpoints were collected using a web-based subjective experiment where the users were asked to select the most informative view of a 3D model.
