The aim of the method presented in this paper is to extract 2-D structural information, called `2-D facets,' in order to compute the 3-D corresponding surfaces. The information obtained by the algorithm is more complete than that obtained by the analysis of characteristic points or segments. The method presented relies on simultaneous analysis of regions and contours. The algorithm first matches the regions of the two images, then a subset of the boundaries of the homologous regions are matched. Finally, the contours detected by an edge extractor are used to improve the previous matching.
