Abstract [en]

We apply elementary techniques from real analysis and singularity theory to derive analytical results for the behaviour in scale-space of critical points and related entities. The main results of the treatment comprise:

  • a description of the general nature of trajectories of critical points in scale-space.
  • an estimation of the drift velocity of critical points and edges.
  • an analysis of the qualitative behaviour of critical points in bifurcation situations.
  • a classification of what types of blob bifurcations are possible.
