1. A method for determining the orientation of a captured digital image, comprising the steps of:
- a) employing a semantic object detection method to detect the presence and orientation of a semantic object in the digital image;
b) employing a scene layout detection method to detect the orientation of a scene layout of the digital image; and
c) employing an arbitration method to produce an estimate of the image orientation by arbitrating between the orientation of the detected semantic object and the detected orientation of the scene layout.

Abstract
A method for determining the orientation of a digital image, includes the steps of: employing a semantic object detection method to detect the presence and orientation of a semantic object; employing a scene layout detection method to detect the orientation of a scene layout; and employing an arbitration method to produce an estimate of the image orientation from the orientation of the detected semantic object and the detected orientation of the scene layout.

11. A system for processing a digital color image, comprising:
-
a semantic object detector to determine the presence and orientation of a semantic object in the digital color image; a scene layout detector to determine the orientation of a scene layout of the digital color image, said scene layout detector having a classifier trained with a plurality of scene prototype images; an arbitrator responsive to the orientation of the semantic object and the orientation of the scene layout to produce an estimate of the image orientation; and an image rotator to re-orient the digital image in the upright direction. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

22. A system for processing a digital image comprising:
-
one or more semantic object detectors, each said semantic object detector being adapted to determine the presence and orientation in the digital image of a semantic object of a respective one of a plurality of different types; a scene layout detector adapted to determine the orientation of a scene layout of the digital image; and an arbitrator adapted to arbitrate between said determined semantic object and scene layout orientations and produce an estimate of an orientation of the digital image. - View Dependent Claims (23, 24, 25, 26)
