Two invariants in edge based stereo analysis

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review

This paper analyzes the relationship between the orientations and the curvature of corresponding edges in a stereo image of a scene. Exact relations are given in case of planar scene surfaces, and it is shown that the shape of the disparity surface is determined by the orientation and curvature attributes. For curved surfaces the invariants are derived for a restricted class of scene curves. Experiments with the orientation invariant are reported.
