The objective of this track is to evaluate the performance of different 3D face recognition techniques. It is based on a new collection of scans, made of an anthropological collection of 130 masks, which have been acquired a century ago. Two sets of scans are made. Each of the 130 masks are scanned by a Roland scanner from a single orientation, and by an Escan scanner from 5 viewing directions.

First, the participant is provided with a training set. Some time before the deadline of submitting the results, the test set and the query set will be made available. For each object from the query set, the participant is required to send an ordered list of retrieved objects from the test set, along with its rank and distance value. This list will be used for the evaluation process. The format of the list can be found here. When performing a single query the user should return the entire list. A participant is allowed to submit up to 5 different lists using different techniques, parameter settings etc. All models will be provided in the Polygon File Format (.ply). There are three data sets: a training set, a test set, and a query set

The training set contains 60 models. These are Roland scans. Download here (25.1 mb).

The testset contains 580 Escans, plus 70 Roland scans, in total 650 scans. See here for an example. Go here to download the complete set.

The query set contains 70 Escan scans from various directions. An example can be found on the left. Please note that the scans acquired may contain holes due to it's pose. Click here to download the files.

The performance will be evaluated using various measures, such as the 1st and 2nd tier Precision and Recall. The F-measure will also be used for evaluation.

Precision is defined as follows: P=(relevant retrieved objects/retrieved objects).

Recall is defined as follows: R=(relevant retrieved objects/total relevant objects).

The F-Measure is calculated using this formula: F=(2*R*P)/(R+P).

The participants must register by sending a message to shrec@cs.uu.nl.

Participants will submit their results using the online submit feature. Up to 5 ranked lists may be submitted as describe above. The format of the result list can be found here.

The participants are required to write a short paper describing their method and commenting the evaluation results.
