<P>PROBLEM TO BE SOLVED: To detect an image including a face of a desired expression which is difficult to define. <P>SOLUTION: An image including a face of a specific expression of a predetermined person is registered beforehand, and feature points representing the contour of the facial components constituting the face in the registered image are extracted. A facial image including the face is detected from the image to be detected, and feature points representing the contour of the facial components constituting the face in the detected facial image. By comparing these feature points, an indicator value representing the positional correlation of the feature points is calculated, and based on the magnitude of the indicator value, whether the detected facial image includes the face of the expression similar to the specific expression is determined. <P>COPYRIGHT: (C)2007,JPO&INPIT |
