5 CONCLUSION AND OUTLOOK
It is quite clear that reasoning in scale space will be a key to
come to a satisfying solution for edge detection and location. To
approach the reasoning we analyzed simulated and real image
data to gain insight into problems of tracking and matching in
multiscale images. Aspects due to the tracking of edges located
by the Fórstner Operator are observed and discussed. Those
edges which can be tracked through a large scale range are most
important for solving the matching process. They may serve for
the elimination of spurious edges and give approximate informa-
tion for matching edges which are missed after smoothing with
a small scale parameter. Further we expect that other knowledge
like smoothness of the displacement field will be a complemen-
tary and helpful information, suited to support the tracking and
matching in combination.
