Does OpenCV support PowerVR SGX540 GPU?

I found from webpage and found "The OpenCV GPU module is a set of classes and functions to utilize GPU computational capabilities. It is implemented using NVIDIA* CUDA* Runtime API and supports only NVIDIA GPUs."

Can I use OpenCV in Pandaboard with GPU support?

As you've discovered, OpenCV uses CUDA technology to speed up processing on the GPUs. For the moment, CUDA is still only supported by NVIDIA GPUs.

For the moment, the answer is no, you cannot enjoy OpenCV's GPU acceleration with PowerVR GPUs because they don't support CUDA.

However, last year OpenCV started working on a OpenCL module. The module is not yet available on OpenCV 2.4.2 but it seems it will be released soon. This is good news for you because it seems that PowerVR SGX530 supports OpenCL.

PowerVR does support OpenCL 1.0, still it is up to the main system-on-chip producer to provide drivers enabling its support. As an example, even if Texas Instruments embeds this GPU within its OMAP4 architecture, no driver is available at the moment, which in turns implies that no OpenCL support is available
