Hi, there, I tried to use OpenCL module in OpenCV3.0, This is official program(under project sample-cpp-(EXAMPLE)facedetect) and could run successfully on Windows 7 (VS2012),
It's Ok when
ocl::setUseOpenCL(false);
However, when ocl::setUseOpenCL(true); or comment it out, error occurred:

# ./facedetect
This program demonstrates the cascade recognizer. Now you can use Haar or LBP features.
This classifier can recognize many kinds of rigid objects, once the appropriate classifier is trained.
It's most known use is for faces.
Usage:
./facedetect [--cascade=<cascade_path> this is the primary trained classifier such as frontal face]
[--nested-cascade[=nested_cascade_path this an optional secondary classifier such as eyes]]
[--scale=<image scale greater or equal to 1, try 1.3 for example>]
[--try-flip]
[filename|camera_index]
see facedetect.cmd for one call:
./facedetect --cascade="../../data/haarcascades/haarcascade_frontalface_alt.xml" --nested-cascade="../../data/haarcascades/haarcascade_eye.xml" --scale=1.3
During execution:
Hit any key to quit.
