Action-estimating device

An action-estimating program installed on a computer storing a plurality of choices of action to be estimated, the program comprising:

• a step for obtaining a plurality of time-series images in which a subject appears;
• a step for detecting a plurality of articulations appearing in each time-series image;
• a step for measuring coordinates of the detected plurality of articulations in each time-series image;
• a step for estimating an action of the subject based on displacement of the coordinates of the measured plurality of articulations in the plurality of time-series images;
• and
• a step for detecting a background appeared in each time-series image,
• wherein, in the estimating step, a probability of each of the plurality of choices is calculated based on the displacement of the coordinates of the measured plurality of articulations in the plurality of time-series images, and the calculated probability of each of the plurality of choices is corrected based on the detected background.

An action-estimating device comprising:

• an estimating-side obtaining unit configured to obtain a plurality of time-series images in which a subject appears;
• an estimating-side detecting unit configured to detect a plurality of articulations appearing in each time-series image;
• an estimating-side measuring unit configured to measure coordinates of the detected plurality of articulations in each time-series image;
• an estimating unit configured to estimate an action of the subject based on displacement of the coordinates of the measured plurality of articulations in the plurality of time-series images;
• a setting unit configured to set a purpose or application for the estimating of the action of the subject;
• and
• a storing unit configured to store a plurality of choices of the action to be estimated,
• wherein, in order to estimate the action of the subject, the estimating unit calculates a probability of each of the plurality of choices based on the displacement of the coordinates of the measured plurality of articulations in the plurality of time-series images, and corrects the calculated probability of each of the plurality of choices based on the set purpose or application.
