Human activities dataset and the ICPR 2012 human activities recognition and localization competition

We describe the LIRIS human activities dataset, the dataset used for the ICPR 2012 human activities recognition and localization competition. In contrast to previous competitions and existing datasets, the tasks focus on complex human behavior involving several people in the video at the same time, on actions involving several interacting people and on human-object interactions. The goal is not only to classify activities, but also to detect and to localize them. The dataset has been shot with two different cameras: a moving camera mounted on a mobile robot delivering grayscale videos in VGA resolution and depth images from a consumer depth camera (Primesense/MS Kinect); and a consumer camcorder delivering color videos in DVD resolution.
