ChaLearn organizes in 2015 two parallel challenge tracks on Age Estimation and Cultural Event Recognition.
Top three ranked participants on each track will be awarded and invited to follow the workshop submission guide for ICCV 2015 workshop for inclusion of a description of their system at the ICCV 2015 workshop proceedings.
This is the second round for this track. We have significantly incremented the number of images and classes, adding a new "no-event" class. As a result, for this track more than 28000 images are labeled with the objective of performing automatic cultural event recognition from 100 categories in still images. These images belongs to 99 different cultural events and one non-class. This is the first dataset on cultural events from all around the globe. The Cultural Event Recognition challenge aims to investigate the performance of recognition methods based on several cues like garments, human poses, objects, background, etc. To this end, the cultural event dataset contains significant variability in terms of clothes, actions, illumination, localization and context.
For each one of the 100 classes, predicting presence/absence of an example of that class in the test image.
A more detailed information is provided on the data section of the competition.
For the evaluation process, the output from your system should be a real-valued confidence so that a precision/recall curve can be drawn. Greater confidence values signify greater confidence that the image contains belongs to the class of interest. The classification task will be judged by the precision/recall curve. The principal quantitative measure used will be the average precision (AP). We use the area under this curve to the computation of the average precision (AP), which is calculated by numerical integration as follows:
In this track, the participants should submit a text file for each category. Each line in the text file should contain a single identifier and the confidence output by the classifier, separated by a space. The predictions TXT files for each category (100 in total) will be put in a single ZIP file and submitted to Codalab.
For example, to the category `La Tomatina', the output of your method should be a file (La_Tomatina.txt) containing the identifiers and confidences for each image:
002234.jpg 0.056313 010256.jpg 0.127031 010987.jpg 0.287153 ...
For this track, we provide a file (evaluate.py) which contains the method for evaluation. This script allows to get the final mean average precision value. In order to ensure the proper operation of the script we need to create the following directory structure:
Track2/ % main directory
Track2/program/ % this folder should contain this script
Track2/input/ref/ % this folder contains the ground truth for validation
Track2/input/res/ % this folder contains the results of the participants for each category (see the format in the previous section)
Track2/output/ % contains the output of the script (a file with the final final mean average precision)
To obtain the final mean average precision (mAP) for all the categories, in the same way performed in the Codalab platform, we must go to the main directory and run the next command:
python program/evaluate.py input output
These are the official rules that govern how the ChaLearn Looking at People 2015 contest promotion will operate. This promotion will be simply referred to as the “contest” or the “challenge” throughout the rest of these rules and may be abbreviated on our website, in our documentation, and other publications as ChaLearn LAP.
In these rules, “organizers”, “we,” “our,” and “us” refer to CHALEARN and MS refer to Microsoft;"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 the contest is split into two competition tracks (with a shared schedule):
Focus of the Contest: thousands of images with the objective of performing automatic age estimation of several people.
All eligible entries received will be judged using the criteria described below to determine winners.
Focus of the Contest: thousands of images with the objective of performing automatic cultural event recognition from tens of categories in still images.
All eligible entries received will be judged using the criteria described below to determine winners.
For all three tracks:
The registered participants will be notified by email of any change in the schedule.
15th June, 2015: Beginning of the quantitative competition, release of development data (Training and Validation sets).
30th August, 2015: Release of encrypted final evaluation data and validation labels. Participants can start training their methods with the whole data set.
7th September, 2015: Release of final evaluation data decryption key. Participants start predicting the results on the final evaluation data. Start predicting the results on the final evaluation labels. Deadline for code submission.
12th September, 2015: End of the quantitative competition. Deadline for submitting the predictions over the final evaluation data. Deadline for code resubmission just if only small changes have been performed (no major changes). The organizers start the code verification by running it on the final evaluation data.
15th September, 2015: Deadline for submitting the fact sheets.
19th September, 2015: Release of the verification results to the participants for review. Top ranked participants are invited to follow the workshop submission guide for inclusion at ICCV 2015 ChaLearn Looking at People workshop proceedings.
