2015-01-07 21:36:06 -0500 asked a question OpenGLES support while building

I'm using Ubuntu running on ARM architecture(ODROID XU3). They say the platform supports only OpenGLES and not the generic OpenGL. How do i enable it while building the OpenCV libraries? Thanks in advance.

i did this. instead of OFF i did not include the statement itself. is that wrong?

i need real time face detection using all the 8 cores. Its ODROID XU3 and running lubuntu. someone guide me please. i'm new to opencv.

2014-11-06 08:45:51 -0500 asked a question opencv compilation in ubuntu with opencl.

i have given

cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL-ES=ON -D WITH_VTK=ON -D WITH_OPENCL=ON -D WITH_FFMPEG=ON ..

even after this, i'm getting 2 frames/sec in the facedetection from the samples/c folder.

2014-11-03 20:47:43 -0500 commented question low frames/sec in odroid xu3.

In general how do i enable openmp for the whole opencv?? No option like that?

2014-11-01 22:57:17 -0500 asked a question low frames/sec in odroid xu3.

turing.py in python2 in the samples folder gives ~ 25 frames/sec in my lappy having core i5. but in xu3 only 2 frames/sec :(

so i googled and found that OpenMP is the best option to boost performance using all the cores.

the odroid xu3 has 8 cores. 4 cores : 2 GHz remaining 4 : 1.4 GHz

I followed these steps when installing in my lappy.

and for opencv with openmp i referred

No improvement at all.

I'm a beginner in linux. Suggestions please.

Try the stable 2.4.9 version. 3.0 is still in the alpha version.

Thank you. I'll try.

2014-10-26 08:46:52 -0500 asked a question Frames/sec improvement in face detection.

Running the default face detection in the samples folder.

In my lappy(CORE i5 - 3.1GHz) running ubuntu 14.04 : 20-25 frames/sec

In ODROID XU3 : Only 2 frames/sec :(

Do i need to configure something?

Wow :) thank you so much. I'm just a beginner. This is perfect.
