since the The 7_CUDALibraries/grabcutNPP and 7_CUDALibraries/imageSegmentationNPP samples have been removed. These samples used the NPP graphcut APIs, which have been deprecated in CUDA 7.5.

Then how to use the grabcut algorithm with the later version？

    Have a look at what was done in OpenCV 3.1 . It had dependencies on the NPP graphcut APIs that needed to be replaced to work with CUDA 8 – talonmies Mar 29 '17 at 05:30

    opencv added an extra definition ' (CUDART_VERSION >= 8000)' [opencv](https://github.com/opencv/opencv/commit/10896129b39655e19e4e7c529153cb5c2191a1db) ,but it didn't solved this problem. @talonmies – ZhaoxingNiu Mar 31 '17 at 12:59
  • OK so the answer is that they disabled it. I was wondering whether they replaced it with something else or not. – talonmies Mar 31 '17 at 13:41

The graphcut APIs in NPP were deprecated and removed during the CUDA 7 release cycle.

There is no direct replacement for them within CUDA (or OpenCV which used the NPP implementation).
