Both OpenCL and CUDA are not supported on Android for now.

Could you tell me, why OpenCL is not supported for Embedded devices yet? In my opinion everything is available for Android OpenCV support (devises,libs...) What is the reason,that it is not possible to use OpenCL with OpenCV in Android?

Probably because OpenCV4Android dev team has other priorities now. But you or somebody else are welcome to contribute OpenCL support for Android.

Hi Andrey - is that still the case? Can't run OpenCV's OpenCL modules on Android devices?

thanks

Hi Andrey - Is Opencv's OpenCL on Android still not available?

OpenCV 3.0 onwards implements UMat which implicitly uses OpenCL acceleration. I'm assuming that writing native code that uses UMat with OpenCV 3.0 (and higher) in C++ and exposing it to Android via JNI and NDK gives you the power of OpenCL on Android devices with OpenCL-enabled GPUs. I'm not sure but maybe someone can confirm that?
