Abstract:
Two problems regarding correspondence between continuous contours and
their representation will be discussed. Both problems are only
partially solved so that proposals of the future research topics are an
important part of the seminar.
The first problem is:
* How fragments of digital contours can be matched to certain contour primitives?
Junctions with multiple arms will be discussed as an example, and two
alternative matching techniques will be discussed. The first technique
is based on a simplified Radon transform, while the second one utilises
moment expressions.
The second problem is:
* How moments of digital contours can be used to estimate properties of the original continuous contours?
Some basic theorems will be presented, and their prospective applications will be discussed (including some open questions).
