2017-08-18 20:14:16 -0500 commented question How to set up opencl in opencv for android

I have the same issue. In my app I'm using useOpenCL() that behaves correctly on Ubuntu but not in my Android app. When I compare an warpAffine() using Mat or UMat, the Android app transform is 7 xs faster using UMat irregardless if I use ocl::setUseOpenCL(false); or ocl::setUseOpenCL(true). It does however make a big difference if I do this on Ubuntu. I'm using opencv 3.2 and the Android Opencv manager.

2016-01-12 20:56:51 -0500 commented answer Triangle detection - Canny failing on corner

Thanks for pointing that out. I tried to set ocl to false but no luck.

>>> cv2.__version__
'3.0.0'
>>> print(cv2.ocl.haveOpenCL())
True
>>> cv2.ocl.setUseOpenCL(False)
>>> print(cv2.ocl.haveOpenCL())
True
>>>
