Hi all! Is it possible to run StereoSGBM disparity estimation on the trunk OpenCV (3.0.0) with OpenCL? I am trying to recover depth from the stereocamera.

I am using OpenCV 3.0.0 from the trunk. Currently my application, running StereoSGBM algorithm, processes one video frame 640x480 for about 1-2 seconds.

Version 2.4.8 of the OpenCV has the separate module OCL, which includes this. It could be concluded that the version 3.0 can automatically turn on OpenCL support. Is it the case?

Here is the relevant part of the buildInformation string:
