Abstract
The depth and orientation of a surface patch relative to a camera are determined. A first and second image of the surface patch are obtained from different viewpoints. Various predicted combinations of depth and orientation values are associated with the surface patch. Different available combinations may have different orientations. Each predicted combination predicts a correspondence between points in the first and second image, corresponding points viewing identical locations on the surface patch. One searches for a best combination of depth and orientation so that among the available combinations the best combination results in a minimum aggregate of differences between pixel values of the first and second image at corresponding points.
