  We consider practical aspects of reconstructing planar curves with prescribed
Euclidean or affine curvatures. These curvatures are invariant under the
special Euclidean group and the equi-affine groups, respectively, and play an
important role in computer vision and shape analysis. We discuss and implement
algorithms for such reconstruction, and give estimates on how close
reconstructed curves are relative to the closeness of their curvatures in
appropriate metrics. Several illustrative examples are provided.
