Internet Mathematics 2011. Determining Image Similarity
More recently, or rather, on May 26, 2011, the results of a very interesting annual competition organized by Yandex - Internet Mathematics 2011 were announced.
The winner of the competition was the team “Mythical Nizhny Novgorod” consisting of: Ilya Lysenkov (captain), Anatoly Baksheev and Maria Dimashova, all - the Itseez company.
In the training stage, which lasted about a month (until the 16th of May), more than 100 teams took part, in the final stage, lasting just one day (from the 16th to the 17th of May) more than 50 teams sent their results.
This year the participants had the following task:
It was given 6000 series of 5 photos each, which were obtained by cutting panoramas from the Yandex.Maps service. In each series there could be photos not from the general panorama (one, two or not). The task was to identify the extra photos in each series.
The main difficulty of the task was that in many pictures there was no clear overlay, these could be photos taken at different angles, with zoom, at different distances to objects, and so on.
In more detail with the terms of the competition, the calculation of the metrics and other details you can find on the competition website: imat2011.yandex.ru
Our team LookLikeIt took 12th place in the final stage with a score of 0.967, which we are very pleased and proud of ourselves with, as we lost to VERY strong opponents.
A little later, we will publish an article describing our methods for solving the problem, if it is interesting.

I want to sincerely thank Yandex for holding such interesting contests and congratulate the winners!
