Method and device for determining face orientation and method and device for reconstructing face image
The invention discloses a face orientation determination method and device and a face image reconstruction method and device. The face orientation determination method comprises the steps of performing principal component analysis processing on an image of a brain region according to a first position, and determining a first direction vector and a second direction vector; aiming at the image of the brain area, determining the front part and the rear part of the brain area according to the distances from voxels at two sides of the first plane to the first plane; the upper portion and the lower portion of the brain area are determined according to the distances from the voxels located on the two sides of the second plane to the second plane; and determining the face orientation according to at least one of the front part of the brain area and the rear part of the brain area, at least one of the upper part of the brain area and the lower part of the brain area, and the first position. According to the method, the face orientation is determined by utilizing the inherent characteristics of the human head structure, and the method has relatively high accuracy..
