Hello everyone!
I was wondering whether cv::cuda::meanStdDev function will be implemented for the CV_32FC1 type in the near future or if it's not in the priority list at all.
I know I can download the image and use the host function (that's exactly my workaround now) but this is very slow and involves a download operation. I'm barely achieiving real-time.
Thanks a lot.
If you are willing to re-compile, it's not that hard to add it. The npp function is there, you just need to add it to the table. And a couple of if statements.
Yep, you need to change some lines, add an if statement or two. The 32F_C1R functions exist, you just need to tell it to use them.
@Tetragramm, I've searched for nppiMeanStdDev32FC1RGetBufferHostSize in "https://developer.download.nvidia.com...", but I couldn't find a solution. How can I use 32FC1 then?
Hi, The same operation of cuda::meanStdDev() on CV_32FC1 can be implemented through the combination of cuda::sum(), cuda::subtract(), cuda::sqrSum().
