Automatic facial landmark detection is a long-standing problem in computer vision and 300-W Challenge is the first event of its kind organized exclusively to benchmark the efforts in the field. The particular focus is on facial landmark detection in real-world datasets of facial images captured in-the-wild. The results of the Challenge will be presented in a special issue of Elsevier Image and Vision Computing Journal.



To facilitate training, the recently collected in-the-wild data sets LFPW [1], AFW [2] and HELEN [3], as well as the controlled lab XM2VTS [4] and FRGC [5] have been re-annotated using a semi-supervised methodology [6] and the well-established landmark configuration of MultiPIE [7] (68 points mark-up, please see Fig. 1). To enhance accuracy, the final annotations have been manually corrected by an expert. Additionally, we provide annotations for the IBUG data set which consists of 135 images with highly expressive faces, difficult poses and occlusions.

All annotations have been made publicly available and can be downloaded from here. Each annotation file has the same name as the corresponding image file. For LFPW, AFW, HELEN,  and IBUG  datasets we also provide the images. The remaining image databases can be downloaded from their authors’ websites. 

Participants are strongly encouraged (but are not restricted) to train their algorithms using the aforementioned training sets and the provided annotations. Should you use any of the provided annotations, please cite [6] and the paper presenting the corresponding database.

Please note that the provided re-annotated data are saved in the Matlab convention of 1 being the first index, i.e. the coordinates of the top-left pixel in an image are x=1, y=1.

Test Database and Face Detection Initialization

Participants will have their algorithms tested on a newly collected data set with 2x300 (300 indoor and 300 outdoor) face images collected in the wild (300-W test set). The test set is aimed to test the ability of current systems to handle unseen subjects, independently of variations in pose, expression, illumination, background, occlusion and image quality. Participants will not have access to the testing data.

As opposed to last year's Challenge (300-W 2013), in this version we will not provide any face detection initializations. Each system should detect the face in the image and then localize the facial landmarks. For this purpose, we have appropriately cropped each test image, so that it includes only one face. Sample examples of such cropped images are shown in Fig. 2. Moreover, some examples of face detection methods can be found in the FDDB benchmark [8] here. Of course participants can use any other face detection method they prefer.

Finally, the range of the Euclidean distance between the eyes' corners in the testing images is [39, 805] pixels. The eyes' corners are represented by points 37 and 46 in the 68 landmark points mark-up of Fig. 1. This range is given in order to facilitate the training of accurate face detection models.

The submitted systems will be evaluated with respect to:

  • Accuracy: Facial landmark detection performance will be assessed on both the 68 fiducial points of the MultiPIE mark-up as well as on the 51 points which are the points without the boundary, as shown in Fig. 1. The average point-to-point Euclidean error normalized by the inter-ocular distance (measured as the Euclidean distance between the outer corners of the eyes) will be used as the error measure. Matlab code for calculating the error can be downloaded from here. Non-detected faces will be assigned an infinite error. The cumulative error rate corresponding to the percentage of test images for which the error was less than a specific value will be produced.
  • Computational Cost: The submitted algorithms will also be ranked with respect to the computational cost. Note that there is an maximum cost limit of 2 minutes for a 640x480 image, measured on a 6-core Intel(R) Core(TM) i7-3930K CPU @ 3.20GHz with 32GB RAM. If the cost for an image exceeds this limit, we will assume that the method has failed for that specific image and an infinite error will be assigned.

Important Dates

  • Binaries validation week (optional): 6-12 October 2014 12-16 January 2015
  • Binaries submission deadline: 15 October 2014 19 January 2015 (extended deadline)
  • Paper submission deadline: 15 December 2014 27 February 2015
  • Acceptance notification: 15 March 2015 The submitted papers are under review.

Please note that these are the valid deadlines; not the ones mentioned on the IMAVIS website.


Submission Information and Format

  • Binaries submission: Participants should send binaries with their trained algorithms to the organizers. Each binary should accept as input the path to the test image (all test images have png format). The output of the binary should be a 68x2 matrix with the detected landmarks. Each such output matrix should be also saved in a file (.pts) with the same ordering and format as the provided annotation files and the same name as the input image filename. If the face is not detected, the output should be either an empty array or NaN and no pts file should be saved. The binaries should be compiled in a 64bit machine and dependencies to publicly available vision repositories (such as OpenCV) should be explicitly stated in a document that accompanies the binary. The binaries must be sent to the participants using the email address:
    The results will be returned to the participants for inclusion in their papers. The binaries submitted for the competition will be handled confidentially. They will be used for the scope of the competition and will be erased after the challenge completion.
  • Binaries validation (optional): A week will be dedicated to validate the binaries functionality. Participants can send their binaries to the organizers during this week in order to validate that they return the expected results on our machines. The submitted binaries will be used to detect the facial landmark points on a small set of images and then both the images and the results will be returned to the participants in order to confirm that the results are the expected ones. This procedure is optional, but highly recommended in order to avoid any possible mistakes during the final evaluation. The binaries should have the format explained in the previous bullet and must be sent to the organizers using the email address: 300faces.challenge@gmail.com.
  • Paper submission: All manuscripts and any supplementary material should be submitted through Elsevier Editorial System (EES). The authors must select as "SI: 300W" when they reach the "Article Type" step in the submission process. The EES website is located at: http://ees.elsevier.com/imavis/.
