Claim One:
1. A face comparison device comprising: an occluded-feature point estimation unit that estimates an occluded-feature point that is a feature point of an invisible face in an input image based on an angle of the face in the input image, a three-dimensional stereoscopic face model, and a model feature point arranged on the three-dimensional stereoscopic model, and outputs position information of the occluded-feature point; a pseudo-feature point estimation unit that estimates a pseudo-feature point that is an erroneously detected feature point that is a feature point of the face not captured within the input image due to occlusion based on the angle of the face in the input image by using position information of the three-dimensional stereoscopic face model that is rotated, and outputs position information of the pseudo-feature point; and a comparison unit that generates a normalized image of the input image by using the position information of the occluded-feature point and the position information of the pseudo-feature point, extracts a first facial feature vector from the generated normalized image of the input image, generates a normalized image of an acquired comparison image, extracts a second facial feature vector from the generated normalized image of the comparison image, and compares the first facial feature vector and the second facial feature vector.
