Due to size limit of shared memory, histogram is built on
the global memory for CV_16UC1 case.
The amount of memory needed for building histogram is:
65536 * 4byte = 256KB
and shared memory limit is 48KB typically.
Added test cases for CV_16UC1 and various clip limits.
Added perf tests for CV_16UC1 on both CPU and CUDA code.
There was also a bug in CV_8UC1 case when redistributing
"residual" clipped pixels. Adding the test case where clip
limit is 5.0 exposes this bug.
* __shfl_up_sync with proper mask value for CUDA >= 9
* BlockScanInclusive for CUDA >= 9
* compatible_shfl_up for use in integral.hpp
* Use CLAHE in cudev
* Add tests for BlockScan
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.
- Substituted HAVE_WINRT with WINRT
- Fixed compilation issues in ocl.cpp and parallel.cpp
- Fixed compiler issue for WP8: "C2678: binary '+' : no operator found which takes a left-hand - Fixed gitignore
- Added #ifdef HAVE_OPENCL to remove compiler warnings in ocl.cpp
- Used NO_GETENV similar to '3rdparty\libjpeg\jmemmgr.c;
- Added ole32.lib for core module (for WindowsStore 8.0 builds)
- Made OpenCV_ARCH aware of ARM
