Methods And Apparatus For Object Detection Within An Image
First Claim
1. A method of estimating an orientation of an object in an image, the method comprising:
- estimating an orientation of the image;
analyzing the image using first and second candidate object orientations to generate respective first and second confidence values; and
estimating the orientation of the object based at least in part on the first and second confidence values,wherein the first candidate object orientation is equal to the estimated image orientation and the second candidate object orientation differs from the first candidate object orientation by a first predetermined angle.

Abstract
A method and device for estimating an orientation of an object, such as a face, within an image. One example method includes estimating an orientation of the image. The image is then analyzed using first and second candidate object orientations to generate respective first and second confidence values. The first candidate object orientation is equal to the estimated image orientation and the second candidate object orientation differs from the first candidate object orientation by a first predetermined angle, such as 180°. The method further includes estimating the orientation of the object based at least in part on the first and second confidence values.
