Does Mali G72 supports OpenCV ?

ureachrama

I want to test enabling of opencv on mali GPU with Android OS, how can we test this ?
And if at all we use any app for testing this, what is the gurantee that it is using GPU ?
Could you please provide your inputs on this ?

    OpenCV is an open-source library built on top of OpenCL 1.2, so any device supporting OpenCL 1.2 *should* support the GPU accelerated back-end just fine. Mali-G72 does indeed support OpenCL 1.2, so I can't see why it wouldn't work as long as your platform ships with Android drivers. Note that OpenCL isn't officially supported on Android and is not a standard part of the NDK, so availability will vary from platform to platform.

    In terms of checking which back-end the OpenCV library is using at run-time, you might consider using the Mali Graphics Debugger - it can trace the OpenCL calls being made by the library - but for an authoritative answer you probably need to ask in the OpenCV developer forums.
