| 英文摘要 |
| This paper investigates the fast eye-localization algorithm without learning. First, in the detected face region,
we setup a certain eye candidate region according to the prior knowledge of the face geometry, and reduce the illumination
on it by using Gaussian difference filter. Next, we define a Haar-like feature to realize the fast eye localization on binary
image, and calculate the evaluation value for the eye candidate region to determine the accurate eye location. This method
we proposed is simple in computation and robust to the disturbances from eye glass frame, eye brow and hair. Because
this algorithm makes use of the prior knowledge of the face geometry, training and learning processes are thus reduced.
Experiments demonstrate that our method can localize eyes fast and accurately, providing the necessary condition for the
face recognition followed. |
