I have built opencv from source with cuda support.

Now I am trying to test it using the resize function of cuda.

I went to the [documentation] and it says to add

#include "opencv2/cudawarping.hpp"

which I did but this time the error is

fatal error: opencv2/cudawarping.hpp: No such file or directory
 #include "opencv2/cudawarping.hpp"

How can I use resize within cuda??


I had a similar problem with the normal resize, that was solved by including 'imgproc.hpp

(https://docs.opencv.org/3.4/db/d29/gr...)

it IS in the cudawarping module and you have to

#include "opencv2/cudawarping.hpp"

(it never says anything about "core" there, you made that up ...)

My mistake. I miswrote the question. (I corrected it already). I did that and the fatal error appeared. cudawarping.hpp does not exist

After that I was trying things and added the "core" but the original one- the one in the documentation- failed

Yes, I did. I followed this: https://www.jetsonhacks.com/2019/11/2... Then with python getBuildInformation I can see that CUDA is active

Apparently there is something wrong with the installation. I reinstalled everything from scratch and now it is working.
