Abstract
A video is analyzed by image processing and the feature parameters of facial expressions and movements, which are extracted in the mouth area. The feature parameter for expressing facial expressions is defined as the average of the facial expression intensity. The parameter for expressing movement of a person is defined as the average of the absolute value of the vertical coordinate for the center of gravity of the mouth area in the relative coordinate system. The experimental result shows the usefulness of the proposed method.
