Hannah McLaughlin	418898029c	Merge pull request #13718 from lochsh:svm-sigmoid-fix SVM sigmoid kernel fix (issue #13621) (#13718) * Added test for sigmoid case for retrieving support vectors * undo unhelpful test * add test for sigmoid SVM with data that is easily separable into two concentric circles * Update sigmoid kernel to use tanh(gamma * <x, y> + coef0) instead of -tanh(gamma * <x, y> + coef0) * remove unnecessary constraint on coef0 * cleanup * fixing inappropriate use of doubles * Add f to float literal * replace CV_Assert with ASSERT_EQ where appropriate	6 years ago
Vadim Pisarevsky	0f622206e4	completely new C++ persistence implementation (#13011 ) * integrated the new C++ persistence; removed old persistence; most of OpenCV compiles fine! the tests have not been run yet * fixed multiple bugs in the new C++ persistence * fixed raw size of the parsed empty sequences * [temporarily] excluded obsolete applications traincascade and createsamples from build * fixed several compiler warnings and multiple test failures * undo changes in cocoa window rendering (that was fixed in another PR) * fixed more compile warnings and the remaining test failures (hopefully) * trying to fix the last little warning	6 years ago
Alexander Alekhin	df8b057b44	avoid `Ptr<> == NULL` checks	6 years ago
Jakub Golinowski	9f1218b00b	Merge pull request #11897 from Jakub-Golinowski:hpx_backend * Add HPX backend for OpenCV implementation Adds hpx backend for cv::parallel_for_() calls respecting the nstripes chunking parameter. C++ code for the backend is added to modules/core/parallel.cpp. Also, the necessary changes to cmake files are introduced. Backend can operate in 2 versions (selectable by cmake build option WITH_HPX_STARTSTOP): hpx (runtime always on) and hpx_startstop (start and stop the backend for each cv::parallel_for_() call) * WIP: Conditionally include hpx_main.hpp to tests in core module Header hpx_main.hpp is included to both core/perf/perf_main.cpp and core/test/test_main.cpp. The changes to cmake files for linking hpx library to above mentioned test executalbles are proposed but have issues. * Add coditional iclusion of hpx_main.hpp to cpp cpu modules * Remove start/stop version of hpx backend	6 years ago
