otherwise model is only ever trained with default
parameters, and digits_adjust does nothing (for example)

finished with NV12 support for D3D11-interop. Now, if texture is in NV12 format then it will be converted to/from BGR UMat.

fixed issues with ocl nv12 cvt kernel

finisged ocl nv12-to-rgba kernel, update dx-interop samples. (ocl rgba-to-nv12 kernel will be added later)

an attempt to fix build issue

fix for non opencl build issue

fix typo

fix compilation warnings

fix compile issue for Mac (OpenCL)

add convertion from rgba to nv12 (still need to debug kernel)

remove empty line at the EOF

fixed compilation warning

Update

misplaced CV_WRAP statement lead to not exposing EM::getCovs() to python/java/matlab wrappers

add a CV_OUT to return the covs properly

Now StereoSGBM behaves similarly to StereoBM in terms of ROI handling.

New mode is approximately 2-3 times faster than MODE_SGBM
with minimal degradation in quality and uses universal
HAL intrinsics. A performance test was added. The accuracy
test was updated to support the new mode.
