OpenCL GPU like ippiRemap function

I am using ipp remap function.

Can you tell me if opencl has GPU optimisation remap function?

Or ipp remap with CPU may be not so slower?

Best regards Viktor.

While there is no single OpenCL function which could do a remap, OpenCV has an OpenCL optimized remap function. It hasn't been optimized specifically for Intel GPUs yet, so we don't have data to suggest a large advantage for the GPU. There are many variables too. The best answer will be for you to run the test yourself using your target system with the data types and image resolutions you need.

Thank you.
