Hi Stéfan,

#1937 highlights a bug in our tests (and failing tests, that aren't currently showing up), so I would consider that the last blocker.

I'll try to get around to #1905, but if I don't that's also OK.

OK ! For #1937, I think the bug highlighted by test_orb.test_keypoints_orb_desired_no_of_keypoints should be fixed before the PR can be merged. Otherwise we'll have Travis failing all the time, for all new PRs. Am I wrong? And many thanks for all the explanations! Cheers, Emma
