International Challenge on Activity Recognition (ActivityNet)

CVPR 2021 Workshop


We are glad to announce the 6th installment of the annual International Challenge on Activity Recognition to be held in conjunction with CVPR21 on June 19, 2021. Since the success of the previous ActivityNet Challenges ( 2016, 2017, 2018, 2019, 2020) and based on your feedback, we have worked hard on making this round richer and more inclusive. We are proud to announce that this year's challenge will be a packed half-day workshop with parallel tracks and will host 12 diverse challenges (16 tasks), which aim to push the limits of semantic visual understanding of videos as well as bridging visual content with human captions.

Two out of the twelve challenges are based on the ActivityNet Dataset. These tasks focus on tracing evidence of activities in time in the form of class labels and captions. In this installment of the challenge, we will host ten guest challenges, which enrich the understanding of visual information in videos. These tasks focus on complementary aspects of the activity recognition problem at large scale and involve challenging and recently compiled datasets: Kinetics-700 (DeepMind), AVA-Kinetics (Google AI, DeepMind), ActEV (NIST), HACS (MIT), Tiny-Virat (UCF), MMAct (Hitachi), Home Action Genome (Panasonic, Stanford), SoccerNet (KAUST), ActivityNet Entities (University of Michigan, Facebook), and VidSitu (USC, UPenn, PRIOR@AI2).
