Planar curves are described by information about corners integrated ov
er various levels of resolution. The detection of corners takes place
on a digital representation. To compensate for ambiguities arising fro
m sampling problems due to the discreteness, results about the local b
ehavior of curvature extrema in continuous scale-space are employed.
