Abstract
In this paper, we propose a set of human perceptual
cues used jointly to automatically detect image orientation. The
cues used are: orientation of faces, position of the sky, brighter
regions, and textured objects, and symmetry. We combine these cues
in a Bayesian framework, and the photo acquiring model has been
considered carefully as the prior knowledge of the image
orientation. Results on more than a thousand different images
provide a compelling argument that our approach is a viable one.
