Hello guys,
I'm quite new in Cuda programming as well. For me it's still quite unclear how to use the CudaMem class. for example how I can do following using page_locked or even zero_copy memory:
Mat srcCpu3ChImg;
Mat outCpu4ChImg;
GpuMat srcGpu3ChImg;
GpuMat outGpu4ChImg;
// load srcCpu3ChImg
srcGpu3ChImg.upload(srcCpu3ChImg);
cv::gpu::cvtColor(srcGpu3ChImg, outGpu4ChImg, CV_BGR2BGRA);
outGpu4ChImg.download(outCpu4ChImg);
thank you a lot in advance cheers greg
