- Return the Hough-Transform for circles with a given radius.
- Centres of circles for a specific radius.
- Produce the Hough transform for lines within regions.
- Compute the Hough transform for lines using local gradient direction.
- Detect lines in edge images with the help of the Hough transform and
returns it in HNF.
- Detect lines in edge images with the help of the Hough transform
using local gradient direction and return them in normal form.
- Select those lines from a set of lines (in HNF) which
fit best into a region.
