Activity Recognition Datasets

An overview of recent action recognition datasets and their detection classes

Concepts & terminologies:

Action: Atomic low-level movement such as standing up, sitting down, walking, talking etc.
Activity/event: Higher level occurence then actions such as dining, playing, dancing
Trimmed video: A short video clip containing event/action/activity of interest
Untrimmed video: A video clip of arbitrary length potentially containing durations without activities of interest
Localization: locating an instance of event/action/activity within a video at a spatial or temporal scale
Spatial localization: Locating the region/area of an instance of action/activity within a video

Notice

Desktop environment sensitivity

The strategy presented below applies to the default desktop environment GNOME3 of Fedora 27, but may not work for others such as KDE Plasma. For instance, KDE tends to crash after installation of NVIDIA drivers. Actually, this is also confirmed by my own recent experience with Fedora KDE Plasma.
