Face and Ocular Challenge Series (FOCS)
The goal of the Face and Ocular Challenge Series (FOCS) is to engage the research community to develop robust face and ocular recognition algorithms along a broad front. Currently the FOCS consists of three tracks: the Good, the Bad, and the Ugly (GBU); Video; and Ocular. These challenges are based on the results of previous NIST challenge problems and evaluations. An overview of the FOCS was given at an invited talk at the IEEE Fourth International Conference on Biometrics: Theory, Applications, and Systems (BTAS 2010). That presentation can be found here.
This website has been created as a resource for researchers tackling the FOCS. The data for the GBU, Video, and Ocular challenges comes as part of the Face and Ocular Challenge Series (FOCS) distribution. . To obtain the FOCS distribution please follow the instructions for the FOCS license on http://www3.nd.edu/~cvrl/CVRL/Data_Sets.html.
The Good, The Bad, and The Ugly (GBU)
Update: A GBU compliant training set used to train the LRPCA baseline algorithm can be downloaded here.
The Good, the Bad, and the Ugly challenge consists of three frontal still face partitions. The paritions were designed to encourage the development of face recognition algorithms that excel at matching "hard" face pairs, but not at the expense of performance on "easy" face pairs.
The images in this challenge problem are frontal face stills taken under uncontrolled illumination, both indoors and outdoors. The three partitions were constructed by analyzing results from the FRVT 2006. The Good set consisted of face pairs that had above average performance, the Bad set consisted of face pairs that had average performance, and the Ugly set consisted of face pairs that had below average performance. There are 437 subjects in the data set. All three partitions have the same 437 subjects. All three paritions have 1085 images in both the target and query sets. After constructing the Good, the Bad, and the Ugly partitions, performance of a fusion alogrithm on the partitions was computed. The performance rates for the verfication rate (VR) @ false accept rate (FAR) = 0.001 are:
The performance results can be seen in both a Bar graph and as an ROC Curve. As you can see the Ugly partition is significantly harder to match than the Good, or the Bad paritions. In order to get the Good, the Bad, and the Ugly data sets researchers will need to:

The Video Challenge is a re-release of the Multiple Biomertic Grand Challenge (MBGC) Video Challenge. This challenge focused on matching frontal vs. frontal, frontal vs. off-angle, and off-angle vs. off-angle video sequences (Powerpoint presentations on the MBGC Video Challenge Version 2 and MBGC Video Challenge Version 1 can be found at the links) The results of the challenge show that video matching is extremely challenging (see slides 9 and 12 in the MBGC Video Challenge Version 2). Due to the difficulty of the MBGC Video Challenge we are keeping this problem open for researchers.
A significant amount research has gone into iris recognition from "high" quality iris images captured from cooperative subjects. The results of this research are commerically available products for matching "high" quality iris images. The cutting edge of research is recognition from images that contain the eye region of the face and the iris. The iris in these images can be of variable quality. This research track is referred to as Ocular recognition to differentiate it from similar recognition problems. The goal of this challenge problem is to encourage the development of Ocular recognition algorithms.
The Ocular Challenge data set consist of still images of a single iris and eye region. These regions were extracted from near infrared (NIR) video sequences collected from the Iris on the Move (IoM) system used in the MBGC Portal Track Version 2 (Powerpoint presentations on the MBGC Portal Challenge Version 2 and MBGC Portal Challenge Version 1 can be found at the links).
