I have a set of 18 images shot handheld in a single row, where APG is having troubles stitching it together.
I discussed the issue in the APG User Forum, but it look s like there is a bug somewhere.
Even if the scene is not of interest to anyone expect me, I think that I should report the problem to the developers
If you look at the attached image you will see that the ends of the pano are overlapping.
This means APG think it's a 360°+ Panorama, but it is not...
I exported them as jpeg to get a smaller Archive for testing...
You can get the archive here
