opencv - How to include and use OpenCv3.1.0 library to CUDA file(.cu)? -

i tried implement own kernel median filter pseudo code:

//main.cpp #include "opencv2/opencv.hpp" cv::mat inputmat = cv::imread() cudamediancaller (inputmat, kernelmat)  //medianfilter.h #include "opencv2/opencv.hpp" cudamediancaller (const cv::mat& inputmat, cv::mat& kernelmat);  //medianfilter.cu cudamediancaller (const cv::mat& inputmat, cv::mat& kernelmat) {     kernelmedianfilter<<< , >>> (uchar3* d_inputmat, uchar* d_kernelmat) }  __global__ void kernelmedianfilter (uchar3* d_inputmat, uchar* d_kernelmat) {  } 

i compile error :

c1083: cannot open include file:'opencv2/opencv.hpp' : no such file or directory

i know .cu file compile nvcc , not compile opencv header filess.

1) how can include opencv3.1.0 library .cu file?

you don't need include opencv in .cu file. need caller api raw pointers , basic data types parameters.

main.cpp

#include "opencv2/opencv.hpp" #include "medianfilter.h"  int main() {   cv::mat inputmat = cv::imread();   .....   cudamediancaller (d_inputmat, d_kernelmat);   .....   return 0; } 

medianfilter.h

cudamediancaller (uchar3* d_inputmat, uchar* d_kernelmat); 

medianfilter.cu

cudamediancaller (uchar3* d_inputmat, uchar* d_kernelmat) {     kernelmedianfilter<<< , >>> (uchar3* d_inputmat, uchar* d_kernelmat) }  __global__ void kernelmedianfilter (uchar3* d_inputmat, uchar* _kernelmat) {  }
