How to use Tan-1 in OpenCV
I want to calculate with this formula
tan-1(Image 1 / Image2)
how to implement it in OpenCV. Thank you.

You should use phase function
Mat xxx = (Mat_<float>(2, 2) << 1, 2, 3, 4);
Mat yyy = (Mat_<float>(2, 2) << 1, 2, 4, 5),angle;
phase(xxx,yyy,angle);
cout<<angle;
results are :
[0.78523159, 0.78523159;
0.92740309, 0.89609587]

Not sure what you're trying to achieve. Calculating atan makes sense only if the Mat objects would contain coordinate values, something like the result of meshgrid in Matlab/Octave. You can't really calculate atan of an image - there is no such thing that I would be aware of.
