Challenges

Thumos logo We have obtained top ranking results in the Thumos 2014 and Thumos 2013 Action Recognition Challenge. The goal of the challenge is to evaluate large-scale action recognition in natural settings. The dataset used is the newly released UCF101 dataset, which is currently the largest action dataset both in terms of number of categories and clips, with more than 13000 clips drawn from 101 action classes.
TRECVID logo LEAR participated together with the AXES project to the TRECVID MED 2013 challenge, and finished in first position. The Multimedia Event Detection (MED) evaluation track is part of the TRECVID Evaluation. The goal of MED is to assemble core detection technologies into a system that can search multimedia recordings for user-defined events based on pre-computed metadata.
