Tom Becker	592f8d8c1b	Merge pull request #10232 from TomBecker-BD:hough-many-circles Hough many circles (#10232) * Add Hui's optimization. Merge with latest changes in OpenCV. * Use conditional compilation instead of a runtime flag. * Whitespace. * Create the sequence for the nonzero edge pixels only if using that approach. * Improve performance for finding very large numbers of circles * Return the circles with the larger accumulator values first, as per API documentation. Use a separate step to check distance between circles. Allows circles to be sorted by strength first. Avoids locking in EstimateRadius which was slowing it down. Return centers only if maxRadius == 0 as per API documentation. * Sort the circles so results are deterministic. Otherwise the order of circles with the same strength depends on parallel processing completion order. * Add test for HoughCircles. * Add beads test. * Wrap the non-zero points structure in a common interface so the code can use either a vector or a matrix. * Remove the special case for skipping the radius search if maxRadius==0. * Add performance tests. * Use NULL instead of nullptr. OpenCV should compile with C++98 compiler. * Put test suite name first. Use different test suite names for each test to avoid an error from the test runner. * Address build bot errors and warnings. * Skip radius search if maxRadius < 0. * Dynamically switch to NZPointList when it will be faster than NZPointSet. * Fix compile error: missing 'typename' prior to dependent type name. * Fix compile error: missing 'typename' prior to dependent type name. This time fix it the non C++ 11 way. * Fix compile error: no type named 'const_reference' in 'class cv::NZPointList' * Disable ManySmallCircles tests. Failing on Mac. * Change beads image to JPEG for smaller file size. Try enabling the ManySmallCircles tests again. * Remove ManySmallCircles tests. They are failing on the Mac build. * Fix expectations to check all circles. * Changing case on a case-insensitive file system Step 1: remove the old file names * Changing case on a case-insensitive file system Step 2: add them back with the new names * Fix cmpAccum function to be strictly weak ordered. * Add tests for many small circles. * imgproc(perf): fix HoughCircles tests * imgproc(houghCircles): refactor code - simplify NZPointList - drop broken (de-synchronization of 'current'/'mi' fields) NZPointSet iterator - NZPointSet iterator is replaced to direct area scan - use SIMD intrinsics - avoid std exceptions (build for embedded systems)	7 years ago

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
