@archit120, thank you! I finally reviewed it. @alalek, I pushed one more commit to archit120/julia_calib3d branch to fix one build problem with UsacParams and also did minor change in one of the examples. For some reason, this new commit does not show up here

There is incident on GitHub: http://status.github.com/
Need to wait for the service repair.

@alalek, thank you! Now the buildbot passed with one error in tracking module; I think, it's not related to the patch.

Thank you for the changes @vpisarev I had somehow not run into that error during my testing.
