The disclosure provides an approach for detecting and localizing action in video. In one embodiment, an action detection application receives training video sequences and associated eye gaze fixation data collected from a sample of human viewers. Using the training video sequences and eye gaze data, the action detection application learns a model which includes a latent regions potential term that measures the compatibility of latent spatio-temporal regions with the model, as well as a context potential term that accounts for contextual information that is not directly produced by the appearance and motion of the actor.
