Qualitative surface shape from deformation of image curves
We describe the constraints placed on the differential geometry of a surface by observing a surface curve from a sequence of positions. In particular two new qualitative results are presented. First, it is shown that sign of normal curvature along the surface curve is determined by tracking image cu...
