The KTH Actions dataset contains six actions (walk, jog, run, box, hand-wave, and hand clap). It is one of the most standard datasets. Each action in the dataset is performed by 25 different individuals, and the setting is systematically altered for each action per actor. Setting variations include outdoor, outdoor with scale variation, outdoor with different clothes, and indoor (s4). These variations test the ability of algorithms to identify actions independent of the background, the appearance of the actors, and the scale of the actors.
