OpenCV 3 RC1 has been released. It has transparent api to run on CPU or GPU.
to make openCV transparent, it uses OpenCL kernels. To run OpenCV on GPU, the GPU should have openCL 1.2 support.
My questions are:
1- Since Mali T6xxx support OpenCL 1.1, is there any documentation on how to adjust OpenCV to work with it?
2- Is there any documentation on how to optimize openCV to work better on Mali GPUs?
3- Does OpenCV works properly on T7xxx which has OpenCL 1.2 support?
4- Is there any other image processing library out there which is optimized for Mail GPUs?
Thanks,
Do you have any sample code that I can run on odroid XU3 and see that openCV code actually runs on GPU?
If it is with openCV 3.0, it is much better, otherwise any other version is sufficient.
If you run any OCL test from the OpenCV unit tests it will run the same algorithm once on the CPU and once on the GPU
Assuming you already have uploaded the "testdata" folder from Itseez/opencv_extra · GitHub to your device, and that you built and installed the android binaries to a "bin" folder, all you need to do is:
for f in `ls bin | grep opencv_test_`; do echo "Running $f ... "; adb push bin/$f /data/ adb shell OPENCV_TEST_DATA_PATH=/sdcard/opencv_testdata /data/$f --gtest_filter=*OCL* adb shell rm /data/$f done
for f in `ls bin | grep opencv_test_`; do
echo "Running $f ... ";
adb push bin/$f /data/
adb shell OPENCV_TEST_DATA_PATH=/sdcard/opencv_testdata /data/$f --gtest_filter=*OCL*
adb shell rm /data/$f
done
