WE HAVE FIXED THE ISSUES, PLEASE REFER TO FORUMS AND CONSIDER SUBMITTING!
The challenge is to build a system that would be able to estimate the head-pose using only depth information from a single Kinect 2 frame of a person sitting in front of a camera. Figure 3 shows an example of the database, where we show high variability in pitch, yaw, and roll values.
Goal of the challenge:
The goal of this challenge is to achieve the minimal average angle estimation error. The team that achieved the lowest score will be deemed the winner. For the different stages of the challenge the dataset will be divided into three main parts: training (28), validation (12) and test (10). All the teams that have reached the final round will be evaluated based on their performance on the test set, with initial training data and validation data forming the input.
PLEASE USE ONLY DEPTH DATA FOR ESTIMATION.
Common terms used in these rules:
These are the official rules that govern how the Joint Challenge on Dominant and Complementary Emotion Recognition Using Micro Emotion Features and Head-Pose Estimation contest promotion will operate. This promotion will be simply referred to as the “contest” or the “challenge” throughout the rest of these rules.
In these rules, “organizers”, “we,” “our,” and “us” refer to iCV; "participant”, “you,” and “yourself” refer to an eligible contest participant.
This is a skill-based contest and chance plays no part in the determination of the winner(s). The goal of one track of the contest is estimating complementary and dominant emotions from the given dataset. The goal of the other track is headpose estimation based on depth data also provided within the competition.

- The organizers will use test data to perform the final evaluation, hence the participants’ final entry will be based on test data.
- Training and validation data:
- The contest organizers will make available to the participants a training dataset with truth labels, and a validation set with no truth labels. The validation data will be used by the participants for practice purposes to validate their systems. It will be similar in composition to the test set (validation labels will be provided in the final test stage of the challenge).
The organizers may also perform additional post-challenge analyses using extra data, but the results will not affect the ranking of the challenge performed with the test data.
- The entries of the participants will be submitted on-line via the Codalab web platform. During the development period, the participants will receive immediate feed-back on validation data released for practice purpose. For the final evaluation, the results will be computed automatically on test data submissions. The performances on test data will not be released until the challenge is over.
