Hello. What are the steps required for accelerating haartraining with OpenCL GPU?

I'm using openCV 2.4.5. I managed to build with OpenCL support, I have a AMD Radeon GPU but I can't figure out how to make the haartrainer use the GPU. My OpenCL detects the GPU correctly. I use the opencv_haartraining binary. Do I need to modify any source code for this to work ?

I did, It all went ver smooth, I compiled with java and opencl support, on ubuntu 12.04.

After removing avcodec run cmake again. then make.

Don't build with avcodec support, try to remove libavcodec if you don't really need it. it seems to be the blocker. apt-get purge libavcodec-*

2013-05-11 18:17:36 -0500 asked a question Java Haar/HOG trainer

Hi. I'm looking for Haar/HOG trainer implementation in java, in order to detect objects in images.

I've seen many examples for using face detection with hog/har but I'd like to recognize other kind of objects.

Can anyone please point me to such an implementation Or to an example for building such a trainer?
