问题
I'm newbie in using Emgu CV and started to create small sample projects, for example face detection, eye detection,..etc. It would be good if I could take the advantage of OpenCL to accelerate the process using gpu. Otherwise, it causes massive cpu utilization when I decrease the scaleFactor. How can I do that? Thanks.

As far as I know (from the official page of Emgu look at the bootom of the page) the UMat image format uses automatically the OpenCL Engine.
First you have to set the OpenCL to true by CvInvoke.UseOpenCL = true, then you need to create a UMat image format and then try to process that image.
At least that's what the official page of Emgu telling.
I tried this and work, it increased the perfomance quite a lot.
