Unable to use CUDA for superresolution

When selecting useGPU=true, superresolution throws the following error:

OpenCV Error: The function/feature is not implemented (The called functionality is disabled for current build or platform) in createSuperResolution_BTVL1_GPU, file /home/scot/opencv-2.4.6.1/modules/superres/src/btv_l1_gpu.cpp, line 58 terminate called after throwing an instance of 'cv::Exception'

I am able to use superresolution without CUDA, although the video speed appears to double with no explanation.

Any ideas?

It means that OpenCV was built without CUDA support. You need to rebuilt OpenCV with CUDA support enabled (set CMake flag WITH_CUDA=ON).

Thank you. I built OpenCV before I installed CUDA, so I am sure that's the culprit. I will rebuild and see what happens.

Reinstalled OpenCV with the CUDA flag you suggested. I got the same errors as in this post:

http://answers.opencv.org/question/20226/opencv2461-compiled-with-cuda-55-cant-compile-cpu/

but added /usr/local/cuda/lib64 to /etc/ld/so/conf as they did and I was able to run using CUDA. Very nice, thank you for your assistance.

Video speed still doubles or quadruples, is this a function of the scale factor? Or is this a problem for which I should start a new thread?
