Paper Abstract

We describe a possibility to reconstruct 3-D information from a single view of an 3-D bilateral symmetric object. The symmetry assumption allows us to obtain a “second view” from a different viewpoint by a simple reflection of the monocular image. Therefore, we have to solve the correspondence problem in a special case, where known feature-based or area-based binocular approaches fail. In principle, our approach is based on a frequency domain template matching of the features on the epipolar lines. During a training period, our system “learns” the assignment of correspondence models to image features. The object shape is interpolated, when no template matches to the image features. This fact is an important advantage of this methodology, because no “real world” image holds the symmetry assumption perfectly. To simplify the training process, we used single views on human faces (e.g. passport photos), but our system is trainable on any other kind of objects.
