FACE-RECOGNITION USING HALF-FACE IMAGES |
摘要 |
Left and right half-face images are processed as independent components in a face-recognition algorithm. To provide compatibility with full-face image recognition systems, mirror-images of the half-face images are used to create full-face images corresponding to each of the left and right half-face images. Each of the created full-face images is compared to a reference full-face image, using conventional face-recognition algorithms. By comparing each of the left-based image and right-based image, the system overcomes the recognition problems that are caused by directional or non-uniform illumination. Alternatively, a composite full-face image can be created based on a blending of the characteristics of each of the left and right half-face images, thereby filtering the illumination variations.
