Hi Qualcomm experts,

I met a bigger problem with GPU, the hardware is  Qualcomm SDM8250 with Qualcomm Adreno 650 GPU.

I want to invoke GPU in some simple operations for image, like resize. but looks below code doesn't work:

cv::UMat uSrc_gpu, uDst_gpu, frameGray_gpu;
cv::Mat image_gpu1 = cv::imread("/data/user/pic/pic5.jpg");
//std::chrono::steady_clock::time_point start_gpu1 = std::chrono::steady_clock::now();
image_gpu1.copyTo(uSrc_gpu);
std::chrono::steady_clock::time_point start_gpu1 = std::chrono::steady_clock::now();
cv::resize(uSrc_gpu, uDst_gpu, newSize, 0, 0, cv::INTER_LINEAR);
cv::cvtColor(uDst_gpu, frameGray_gpu, cv::COLOR_BGR2GRAY);
cv::equalizeHist(frameGray_gpu, frameGray_gpu);

and use function cv::ocl::haveOpenCL() to check, also shows not available.

so can you help to provide a guide how to do it?

just to invoke GPU during image resize operations.

Thanks a lot.

Br.

Michael
