SHREC'09 track: querying with partial models

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.

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 queries either consists of partial 3D models or of range images. The participants may present ranked lists for either of the query sets or both. There is no obligation to submit rank lists for both of the query sets.

Dataset

The first query set consists of 20 3D partial models which are obtained by cutting parts from complete models. The objective is to retrieve the models which the query part may belong to. The file format to represent the partial query models is the ASCII Object File Format (*.off).

This second query set is composed of 20 range images, which are acquired by capturing range data of 20 models from arbitrary view directions. The range images are captured using a desktop 3D scanner. The file format is in the ASCII Object File Format (*.off) representing the scan in a triangular mesh.

The target database is the same for both of the query sets and it contains 720 complete 3D models, which are categorized into 40 classes. In each class there are 18 models. The file format to represent the 3D models is the ASCII Object File Format (*.off).D Models, Classification files, Evaluation software, Images

A Benchmark for Automatic Best View Selection of 3D Objects

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.

The 3D object dataset consists of 68 triangular meshes. Some of the models are standard models that are widely used in 3D shape research; and they have been used as test objects by researchers working on the best view problem.

A web-based interface is used in the experiments. The user is shown the 68 3D models one at a time. Each model is initially rendered with a random pose. The user is asked to rotate the model via dragging the mouse into a view that he/she thinks is the best, and then to click on the submit button. 26 participants have submitted their preferred best views for the 68 models. For each model, we provide an ASCII file containing the view-points selected by the human subjects.

Our evaluations take into account the symmetry sets of the viewpoints. We have used the Fourier-Mellin image matching technique to determine symmetries in the object with respect to a particular view-point.

Evaluation of 3D Interest Point Detection Techniques via Human-generated Ground Truth

This benchmark aims to provide tools to evaluate 3D Interest Point Detection Algorithms with respect to human generated ground truth. Please refer to the paper for more information about this benchmark: "Helin Dutagaci, Chun Pan Cheung, Afzal Godil: Evaluation of 3D interest point detection techniques via human-generated ground truth", The Visual Computer, 2012.Using a web-based subjective experiment, human subjects marked 3D interest points on a set of 3D models. The models were organized in two datasets: Dataset A and Dataset B. Dataset A consists of 24 models which were hand-marked by 23 human subjects. Dataset B is larger with 43 models, and it contains all the models in Dataset B. The number of human subjects who marked all the models in this larger set is 16.We have compared five 3D Interest Point Detection algorithms. The interest points detected on the 3D models of the dataset can be downloaded from the link next to the corresponding algorithm.

Tool for Evaluation of Vaporized Hydrogen Peroxide Disinfection of N95 Masks in Rooms

The SARS-CoV-2 virus has put a strain on the supply and distribution of N95 masks, with some hospitals electing to reuse masks after disinfection. Currently, vaporized hydrogen peroxide (VHP) mask disinfection systems are being deployed at multiple locations throughout the United States, for example in shipping containers and in small rooms. Such enclosures will be of a different size, have different surface materials and have varying air change rates; all these parameters will impact the VHP dose that the masks receive. This spreadsheet tool can be used to estimate the VHP concentration in air of such a room. The tool employs a single-zone mass balance analysis that accounts for room size, VHP losses to surfaces and air change rate. This tool is intended to support VHP disinfection efforts by providing estimates of VHP concentrations in the room being employed, but it does not describe or provide guidance on VHP disinfection applications.

Multi-spectrum Analysis Tool for Spectroscopy (MATS)

The purpose of the MATS project is to develop a NIST-based multi-spectrum fitting tool for spectroscopic data that allows the flexibility to test and adapt to experimental/data-driven needs.  This software allows for the use of several commonly used spectroscopic line profiles (Voigt, Nelkin-Ghatak, speed-dependent Voigt, speed-dependent Nelkin-Ghatak, and Hartmann-Tran) and allows for pressure, temperature, and composition constraints to be imposed on solutions.  In addition to fitting experimental spectra, MATS can generate simulated spectra, which allows for its use as an error analysis tool.  The tool uses existing python applications such as the HITRAN Application Programming Interface (HAPI) and LMFit as the engine for spectral fitting.

NIST/SEMATECH e-Handbook of Statistical Methods (NIST Handbook 151)

The NIST/SEMATECH e-Handbook of Statistical Methods is a Web-based book written to help scientists and engineers incorporate statistical methods into their work as efficiently as possible. Ideally, it will serve as a reference which will help scientists and engineers design their own experiments and carry out the appropriate analyses when a statistician is not available to help. It is also hoped that it will serve as a useful educational tool that will help users of statistical methods and consumers of statistical information better understand statistical procedures and their underlying assumptions, and more clearly interpret scientific and engineering results stated in statistical terms.

EDGe$ (Economic Decision Guide Software) Online Tool, Version 1.0

Designed to support community-level resilience planning, the powerful online EDGe$ Tool, Version 1.0 assists in selecting cost-effective community resilience projects. Produced by the National Institute of Standards and Technology (NIST), the EDGe$ platform-independent app can help community planners and resilience officers, as well as economic development, budget, and public works officials.

EDGe$ provides a standard economic methodology for evaluating investment decisions required to improve the ability of communities to adapt to, withstand, and quickly recover from natural, technology, and human-caused disruptive events. The tool helps the user to identify and compare the relevant present and future resilience costs and benefits associated with new capital investment versus maintaining a community?s status-quo. Benefits include cost savings and damage loss avoidance because enhancing resilience on a community scale creates value, including co-benefits, even if a hazard event does not strike.

EDGe$ is based on the process found in NIST?s Community Resilience Economic Decision Guide for Buildings and Infrastructure Systems (EDG). The EDG and EDGe$ can be used as standalone tools, but are designed as part of a more comprehensive planning process and in combination with the NIST Community Resilience Planning Guide for Buildings and Infrastructure Systems.

Dataset from Steel-Concrete Composite Floor Systems Subject to Fire - Phase 1

Experimental fire tests were conducted on four 12.8 m long steel-concrete composite floor beam assemblies with varying end support conditions, including two types of simple shear connections (shear tabs or welded-bolted double angles) and slab end continuity. Each specimen was constructed as a partially-composite beam, consisting of a lightweight concrete slab on formed metal decking supported by a W18x35 steel beam acting compositely via 19 mm diameter headed stud anchors spaced 305 mm. While resisting an ASCE 7-specified gravity load using hydraulic actuators, each specimen was exposed to a structurally significant  fire that was produced using three natural gas-fueled burners distributed on the floor of the test compartment with the maximum heat release rate of 4 MW. Imposed mechanical loading and fire characteristics, thermal and structural responses, and structural failure modes of the specimens were studied.

Data for "Frequency-comb spectroscopy on pure quantum states of a single molecular ion"

These data files contain the data for the measured transition frequencies shown in Table I and the traces in Figure 3 of the publication "Frequency-comb spectroscopy on pure quantum states of a single molecular ion," accessible at https://arxiv.org/abs/1911.12808. In this publication we use generally applicable quantum-logic techniques to prepare a trapped molecular ion in a single quantum state, drive terahertz rotational transitions with an optical frequency comb, and read out the molecular state non-destructively, leaving the molecule ready for further manipulation. 

One file contains data For Table 1. In the measurement of rotational transition frequencies, the intensities of the comb beams are varied to characterize the effect of AC Stark shift, while the intensity ratio between the sigma and pi polarized beams are kept at close to 2. The average intensity of the  sigma-polarized comb beam is quantified by measuring the resultant Stark shift,  fSS_sigma, on the 729 nm transition of the Ca+ ion, with the Ca+ ion where the CaH+ ion would be during rotational spectroscopy experiments. 

The other file contains data for Figure 3, (a) Spectra for the J = 4 to 2 transition: 40CaH+ is prepared in J = 2, followed by a pulse train from the comb Raman beams probing the J = 2 to J = 4 transition. After the probe pulse train, projective measurements of both initial and final states are performed and the state occupation probability is determined. The probe time is ~1.6 ms. The frequency shows the offset of the Raman difference frequency from the resonant value. (b) Rabi flopping on the J = 4 to J = 2 transition: Starting in J = 4, with the comb Raman pulse detuning set to resonance, the state of the 40CaH+ ion is driven coherently to J = 2  by a pulse train of variable duration from the comb Raman beams. The center wavelength of the frequency comb was ~800 nm for these spectra and Rabi flopping traces. The error bars stand for ±1 standard deviation.

Aged Body Armor- Linking Theory to Practice by Predicting Ballistic Performance from Mechanical Properties

We present correlations found between the tensile strengths of yarns extracted from armor and the V50 ballistic limit when significant degradation of the mechanical properties of the extracted yarns was observed. These studies provided the basis for a validation dataset from which we compare the experimentally measured V50 ballistic limit results to the theoretically predicted V50 results. This approach is promising for the development of a tool for fielded-armor-performance surveillance relying upon mechanical testing of armor coupon samples. 

There are 3 datasets included. The first dataset consists of failure strength and failure strain for yarns extracted from aged ballistic vests, where the vests were aged in laboratory accelerated ageing conditions. The second dataset consists of failure strength for yarns extracted from aged vests, where the vests were aged in the field. The third dataset consists of V50 measurements on vests that were aged using an accelerated laboratory protocol.

SRM 1450 Fibrous Glass Board: Retrospective Analysis

Thermal conductivity data acquired previously for the establishment of Standard Reference Material (SRM) 1450, Fibrous Glass Board, as well as subsequent renewals 1450a, 1450b, 1450c, and 1450d, are re-analyzed collectively and as individual data sets.  Additional data sets for proto-1450 material lots are also included in the analysis (eleven data sets in total). The data cover the years 1958 to 2009; 52 years of activity by the National Institute of Standards and Technology (NIST) in developing and providing thermal insulation SRMs, specifically high-density molded fibrous-glass board, to the public. Collectively, the data sets cover two nominal thicknesses of 13 mm and 25 mm, bulk densities from 60 kg/m3 to 180 kg/m3, and mean temperatures from 100 K to 340 K.  The prevailing generic model for the majority of data sets is the bilinear model in density and temperature.  The regression equations are not intended to be, and cannot be, used to "re-certify" any of these previous SRMs. The results of this analysis, instead, aim to enhance our understanding of the original certificate equations derived by previous NIST (formerly the National Bureau of Standards) researchers as well as to improve the development and modeling of future thermal insulation SRMs.
