Is it possible to access OpenCV OCL (OpenCL) methods from python (cv2)?
unfortunately, - no way.
opencv uses special Mat types for this, ocl::Mat or cuda::Mat , 
and those are not exposed to the wrappers (so, same problem for java and matlab)
From what I can tell, there's no way to access OpenCV's OpenCL (OCL) module from the python cv2 bindings.  Does anyone know of a straightforward way to do this?
