Abstract: In the behavior estimation device, a person feature extraction means extracts a feature of a person detected from a plurality of images in a time series. An object feature extraction means extracts a feature of an object detected from the plurality of images. A peripheral feature extraction means extracts a feature of a periphery of the person in the plurality of images. A feature aggregation means executes aggregation processing for aggregating the feature of the person, the feature of the object, and the feature of the periphery of the person. A behavior estimation processing means executes estimation processing for estimating the person's behavior included in the plurality of images based on information including a processing result of the aggregation processing.
