cuda_canny : multi stream safety (#11483)
* CUDA_ImgProc/Canny Asynchronous test
* cuda_canny : multi stream safety (1/3)
- Convert global variable canny::counter to class local variable
* cuda_canny : multi stream safety (2/3)
- Use texture objects rather than texture reference for cc >= 3.0,
since texture reference must be declared as a static global variable
which results in race condition when ran concurrently
* cuda_canny : multi stream safety (3/3)
- Refrain from using global variable in row_filter and column_filter
(converts column_filter::c_kernel and row_filter::c_kernel to local
variables)
* Fixes#11193
- removed tr1 usage (dropped in C++17)
- moved includes of vector/map/iostream/limits into ts.hpp
- require opencv_test + anonymous namespace (added compile check)
- fixed norm() usage (must be from cvtest::norm for checks) and other conflict functions
- added missing license headers
Implement cv::cuda::calcHist with mask support (#8367)
* Implement cuda::calcHist with mask
* Fix documentation build warning
* Have their own step sizes for src and mask. Fix review comment.
