Alexander Alekhin	0ed3209b00	ocl: avoid unnecessary loading/initializing OpenCL subsystem If there are no OpenCL/UMat methods calls from application. OpenCL subsystem is initialized: - haveOpenCL() is called from application - useOpenCL() is called from application - access to OpenCL allocator: UMat is created (empty UMat is ignored) or UMat <-> Mat conversions are called Don't call OpenCL functions if OPENCV_OPENCL_RUNTIME=disabled (independent from OpenCL linkage type)	7 years ago

Gregory Morse	d30a0c6f03	Merge pull request #9856 from GregoryMorse:patch-1 * Update OpenCVCompilerOptimizations.cmake Neon not supported on MSVC ARM breaking build fix * Update OpenCVCompilerOptimizations.cmake Whitespace * Update intrin.hpp Many problems in MSVC ARM builds (at least on VS2017) being fixed in this PR now. C:\Users\Gregory\DOCUME~1\MYLIBR~1\OPENCV~3\opencv\sources\modules\core\include\opencv2/core/hal/intrin.hpp(444): error C3861: '_tzcnt_u32': identifier not found * Update hal_replacement.hpp Passing variadic expansion in a macro to another macro does not work properly in MSVC and a famous known workaround is hereby applied. Discussion of it: https://stackoverflow.com/questions/5134523/msvc-doesnt-expand-va-args-correctly Only needed the fix for ARM builds: TEGRA_ macros are used for cv_hal_ functions in the carotene library.

Tomoaki Teshima	139b32734e	Merge pull request #9714 from tomoaki0705:universalBilateral imgproc: use universal intrinsic as much as possible (#9714) * use universal intrinsic as much as possible * make SSE3 part as common as possible with universal intrinsic implementation * put the reducing part out of the main loop * follow the comment * fix the typo * use v_reduce_sum4 * follow the comment again * remove all CV_SSE3 part from smooth.cpp	7 years ago
Peter Fischer	332588fcee	Fix bug: non-maximum suppression for hough circle The non-maximum suppression in the Hough accumulator incorrectly ignores maxima that extend over more than one cell, i.e. two neighboring cells both have the same accumulator value. This maximum is dropped completely instead of picking at least one of the entries. This frequently results in obvious circles being missed. The behavior is now changed to be the same as for hough_lines. See also https://github.com/opencv/opencv/issues/4440	7 years ago
