  • Publication number: 20250054339
    Abstract: An action localization apparatus acquires a target clip and detects persons from the target clip. The action localization apparatus generates a person clip from the target clip for each of the persons detected from the target clip, and extracts a feature map from each of the person clip. The action localization apparatus computes, for each of predefined action classes, an action score that indicates confidence of an action of that action class being included in the target clip based on the feature maps extracted from the person clips, and localizes each action whose action class has the action score larger than or equal to a threshold by performing class activation mapping on each of the person clips.
