On the behaviour in scale-space of local extrema and blobs
1991 (English)In: Scandinavian Conference on Image Analysis: SCIA'91 (Aalborg, Denmark), 1991, 8-17 p.Conference paper (Other academic)
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.
