Abstract. We report here on the use of two novel quantities. the shape index and the curvedness, in shape-from-stereo measurements. In a recognition task experiment subjects are able to categorize shapes which are shown as random dot stereograms on the basis of their shape index. We also find that shape perception in the investigated region is scale independent. Detection of hyperbolic surfaces is not as good as detection of elliptic surfaces.
