Abstract
A method for detecting a plurality of object regions in an image, wherein the plurality of object regions having similar specific structural features, comprises: an estimation step for estimating a common initial value for the specific structural features of the plurality of object regions; and a determination step for determining, for each of the plurality of object regions, a final value for the specific structural feature of the object region and a final position thereof separately based on the estimated common initial value.

A method for detecting a plurality of object regions in an image, the plurality of object regions having similar specific structural features, the method comprising:
- an estimation step for estimating a common initial value for the specific structural features of the plurality of object regions;
- and
- a determination step for determining, for each of the plurality of object regions, a final value for the specific structural feature of the object region and a final position thereof separately based on the estimated common initial value.
A method for detecting two eye pupil regions in a face image, the two eye pupil regions having similar radii, the method comprising:
- an estimation step for estimating a common initial value for the radii of the two eye pupil regions;
- and
- a determination step for determining, for each of the two eye pupil regions, a final value for the radius of the eye pupil region and a final center of the eye pupil region separately based on the estimated common initial value.
