On the behaviour in scale-space of local extrema and blobs
1991 (English)In: Theory and Applications of Image Analysis: Selected Papers from the 7th Scandinavian Conference on Image Analysis (Aalborg, Denmark, 1991) / [ed] P. Johansen and S. Olsen, World Scientific, 1991, 38-47 p.Chapter in book (Refereed)
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.
