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.
Claims26
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.
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.
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.
