Submission protocol

In order to join the MICHE-II competition, each participant is asked to submit a registration form first. Once correctly registered, the participant can also submit more than one executable application.

Registration (here)

  1. Each participant must fill and submit a registration form.
  2. Each submission is associated to a username chosen by the participants. The username will be also used as a name for the submitted executable.
  3. Each participant is allowed to submit more than a single executable or multiple separated variants of the same algorithm. In case of multiple submissions, only one registration form is required.

Executable

  1. MICHE-II is a challenge for iris recognition on MICHEDB (a dataset of images grabbed by mobile devices and available online here). Each executable should therefore be able to receive from command line a pair of images from the dataset and a pair of corresponding segmentation masks and should produce a score in terms of dissimilarity between the two irises.
  2. The order of inputs is strictly defined. Let I1 = image1Filename.ext be the first RGB image containing an iris and M1 = mask1Filename.ext the corresponding binary mask. Let I2 = image2Filename.ext be the second RGB image containing and iris and M2 = mask2Filename.ext its corresponding mask. Let path be the directory for matching restults. Let APP be the executable application, then by running:

    APP I1 M1 I2 M2 path

    a TXT file containing the dissimilarity_score is then created. Such TXT file must have the following properties:
    1. it is saved in path (preferably something like "./results")
    2. its filename is image1Filename_image2Filename.txt (NOTE. filenames without file extensions)
    3. its content is image1Filename [whitespace] image2Filename [whitespace] dissimilarity_score (NOTE. filenames without file extensions)
  3. The dissimilarity score is meant as the probability that two irises are from two different subjects. The higher is the dissimilarity the higher is the probability that the two irises are not from the same person. Let I be set of images from MICHEDB, the dissimilarity function D is defined as:

    where

    and satisfies the following properties:


  4. The participants can use the whole MICHEDB dataset for developing and performing experimentations of their proposed algorithm. The participants should take into account that the dataset is going to be extended with new acquisitions by new mobiles and of new subjects according to the same acquisition protocol applied to the current version of the database. The challenge will be run on a subset of the new version of MICHEDB that will be revealed together with the final ranking.
  5. Participants must consider that the best segmentation algorithm submitted to MICHE-I will be used to generate the binary masks. Since it will be used also for the final ranking of submitted algorithms, participants are invited to use it for testing their proposal.
    The Unsupervised detection of non-iris occlusions (by Haindl et al) is available for download here. For details of the algorithm, refer to the article published and available on-line in Elsevier Pattern Recognition Letters Journal.
  6. Each executable is supposed to be self-contained and it will not have access to the Internet. No any additional download has to be expected to run the application. The submitted proposal must therefore contain all supporting files (dlls, libraries and so on) useful to its proper running.
  7. The executable can be written in any programming language and should run on one of the following operating systems: (1) Windows 7 64/32 bit, (2) Linux Ubuntu 14.04. Code written in Matlab is also acceptable at condition that it runs on Matlab 2013. In case of any special setting needed for the proper running of the algorithm, a README file is expected.
  8. Executables that do not match the requirements above could be discarded from the contest at the discretion of the Evaluating Committee.

  9. Executables must be sent by the email address chosen for the registration to biplab@unisa.it. Please, put the chosen username in the subject of the email. In case of multiple submissions, please report details of the algorithm in the body of the email.
