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.
