Hi everyone,

Do you know what is different between Mali OpenCL SDK and OpenCL in OpenCV library. I see that in Mali OpenCL SDK has some detail sample code about how to create Memory buffer, get input data, setup argument... But in OpenCL inside OpenCV library, I only need change from Mat to UMAT to have OpenCL code run on GPU? and it seems OpenCL code hidden under API? How can I change OpenCL code by my application?

Thank you very much for your sharing.

In my opinion:

Mali OpenCL SDK contains the OpenCL driver to be able to run OpenCL code on Mali GPU, like Intel OpenCL driver is to be able to run OpenCL code on Intel iGPU or Nvidia OpenCL driver for Nvidia GPU
OpenCL OpenCV is just some OpenCL code (similar to C++ OpenCV code in term of sentence)

So. How we modify OpenCL code on OpenCL to do our application?

In OpenCV we use T-API, which is a transparent API that selects the OpenCL implementation of a function if there is OpenCL enabled and if OpenCL capable hardware is available. This allows users to ignore using specific functions for OpenCL optimized directives.
