Status in Hugin - Panorama Tools GUI: Fix Released

Bug description:
Dear Hugin Staff,
I would want to propose to you an user interface and a simple algorithm in order to simplify the creation of control points with photographies that overlap in miscellaneous way.

We suppose of to have taken the photos of a panorama with a not-wide angle optic. Therefore, for being able to cover the vertical extension, three series have been made, heading up, low and to the center.

The photos that are obtained not only overlap from right towards left (or left to right) but also up and down. I have noticed that autopano does not manage such situation at best.

Currently I have resolved the problem selecting the overlapping photographies by hand and then launching every time the creation of the control points. It works well, but it is boring and it is easy to mistake.

I have thought, therefore, that he would be interesting to have a section of hugin where to be able to indicate which pairs of photographies are overlapped, so that hugin can, automatically, launch autopano on the correct sets of overlapping photographies.

For an example I attached a proposal of interface for being able to perform this selection.

Obviously the more problematic part is managing the undirected graph that it is obtained with this method.
I would propose to proceed with the following algorithm:

Prerequisite: we have the graph where node(n)='photo n' and arc(a,b)='photo a and b are overlapped'. The graph is created using data supplied by user using the proposed interface.

  for each photo p
    clear set S
    insert p into the set S 
    for each neighbor n of node(p)
       insert n into the set S
    launch autopano on photos in S

where 'neighbor' represents a metric on the graph. The simplest one is consider 'neighbors' of node(p) those nodes m for which exists the relation  arc (p, m).

Obviously such operation is not necessary if the user not have necessity of a thus precise control of the creation of the control points.

Hoping of being be useful to you and to have marked an interesting request,
Yours respectfully
Filippo Pagin
