[Vxl-maintainers] RE: vil1_from_vil_image_view (question re: edge detection)

[Joseph L M. <mu...@le...>]

I wasn't thinking about adding to vgl but adding a new library that
builds on vgl.  We need region boundaries and other geometric relations
as well.

If these edgel structures are only used (and useful) for segmentation,
it's maybe better to have them in the same library as the segmentation
algorithms.
That will also minimise dependencies, and avoid overloading vgl with
too specific stuff.
