One major challenge for this task is that when an actor performs an action, different body parts of the actor provide different types of cues for the action category and may receive inconsistent action labeling when they are labeled independently.

We propose an efficient online video filtering method, called adaptive exponential filtering (AES) to refine pixel prediction maps.
