Error while running an example from Readme

[ducha-aiki]

Hi,
I ham running this code

init; % add project paths, add solver aliases etc.
img_path = 'data/img1.jpg'; % specify a path to an image
solvers = [Solver2PC4CA, Solver6CA]; % define the solver(s)
autocalib(img_path, solvers); % run auto-calibration

And get following error:

>>>>>> Image: img1.jpg
Error using cmp_argparse (line 71)
Unknown parameter 'low'.

Error in get_rgns (line 4)
    cfg = cmp_argparse(cfg, varargin{:});

Error in autocalib (line 44)
            [rgns,Gapp] = get_rgns(img, arc_cfg{:},...

My matlab version is 8.5.0.197613 (R2015a)

Hi @ducha-aiki,
Thanks for reporting an error! There was a small bug that should be fixed now. Could you please pull and run it again.

OK, it looks like that the problem is in my matlab version. I tried a newer one and got a different error :(

Сan you specify your Linux version?

The problem seems similar to this one. Could you please check if your OS and compiler are the same as there (Ubuntu 14.04, gcc 5.5). If yes, then downgrading gcc to 4.9 might help. You might also try to re-build edgeSubPix with changed CMakeLists.txt according to that solution (or maybe try to just re-build first)
