I like to use imshow in opencv function for debugging. in my case in ecc.cpp my guess is that I should include highgui.hpp, but I cannot figure out how to do it.

there is no ecc.cpp in the opencv codebase. and we don't know, what you're talking about.

can you show the code you're trying with ?

i somehow doubt, that this is a good idea, but technically it is not a problem.

you can #include <opencv2/highgui.hpp> in the ecc.cpp code (before the namespace), but you also have to add a dependancy to the highgui lib so it looks like:

ocv_define_module(video opencv_imgproc opencv_highgui OPTIONAL opencv_calib3d WRAP java python js)

then you have to re-run cmake (mandatory, because you changed the module dependancies !) and rebuild the opencv libs.

above procedure will just cost you an hour or so ....
