Estimating the term…
A plurality of different facial images is used to cause a face classification apparatus to learn a characteristic feature of a face by using a machine-learning method. Each of the facial images includes a face which has the same direction and the same angle of inclination as those of a face included in each of the other facial images and each of the facial images is limited to an image of a specific facial region. For example, the facial region is a predetermined region including only a specific facial part other than a region below an upper lip to avoid an influence of a change in facial expressions. Alternatively, if the apparatus is used to detect a frontal face and to perform refined detection processing on the extracted face candidate, a region including only an eye or eyes, a nose and an upper lip is used as the facial region.
A learning method for causing a face classification apparatus to learn a characteristic feature of faces, wherein the face classification apparatus is an apparatus for classifying whether an input image is a facial image including a face which has a predetermined direction and a predetermined angle of inclination, wherein the characteristic feature of faces is learned by using a machine-learning method using a plurality of facial images for learning, which are different from each other, and each of which includes a face which has the predetermined direction and the predetermined angle of inclination, and wherein the plurality of facial images for learning includes only images of a predetermined facial region, determined based on at least one of the predetermined direction and the type of processing in face detection processing in which the face classification apparatus is used.
A learning apparatus for causing a face classification apparatus to learn a characteristic feature of faces, wherein the face classification apparatus is an apparatus for classifying whether an input image is a facial image including a face which has a predetermined direction and a predetermined angle of inclination, wherein the characteristic feature of faces is learned by using a machine-learning method using a plurality of facial images for learning, which are different from each other, and each of which includes a face which has the predetermined direction and the predetermined angle of inclination, and wherein the plurality of facial images for learning includes only images of a predetermined facial region, determined based on at least one of the predetermined direction and the type of processing in face detection processing in which the face classification apparatus is used.
A computer readable recording medium having stored therein a program that causes a computer to perform processing for causing a face classification apparatus to learn a characteristic feature of faces, wherein the face classification apparatus is an apparatus for classifying whether an input image is a facial image including a face which has a predetermined direction and a predetermined angle of inclination, and wherein the characteristic feature of faces is learned by using a machine-learning method using a plurality of facial images for learning, which are different from each other, and each of which includes a face which has the predetermined direction and the predetermined angle of inclination, and wherein the plurality of facial images for learning includes only images of a predetermined facial region, determined based on at least one of the predetermined direction and the type of processing in face detection processing in which the face classification apparatus is used.
