Tomoaki Teshima	07c3aae315	let the test pass on Mali G52 (ODROID-N2)	5 years ago
Alexander Alekhin	be17f532e1	imgproc(resize): fix resizeNNInvoker handling of generic pixel size	5 years ago
Alexander Alekhin	0fb4f2cc9c	imgproc: add src.empty() checks in filter operations	5 years ago
Vadim Pisarevsky	8f3867756c	Merge pull request #16594 from vpisarev:hull_ordering_fix fixed the ordering of contour convex hull points * partially fixed the issue #4539 * fixed warnings and test failures * fixed integer overflow (issue #14521) * added comment to force buildbot to re-run * extended the test for the issue 4539. Check the expected behaviour on the original contour as well * added comment; fixed typo, renamed another variable for a little better clarity * added yet another part to the test for issue #4539, where we run convexHull and convexityDetects on the original contour, without any manipulations. the rest of the test stays the same	5 years ago
Vadim Pisarevsky	07b475062f	Merge pull request #16608 from vpisarev:fix_mac_ocl_tests * fixed several problems when running tests on Mac: * OCL_pyrUp * OCL_flip * some basic UMat tests * histogram badarg test (out of range access) * retained the storepix fix in ocl_flip only for 16U/16S datatype, where the OpenCL compiler on Mac generates incorrect code * moved deletion of ACCESS_FAST flag to non-SVM branch (where SVM is shared virtual memory (in OpenCL 2.x), not support vector machine) * force OpenCL to use read/write for GPU<=>CPU memory transfers on machines with discrete video only on Macs. On Windows/Linux the drivers are seemingly smart enough to implement map/unmap properly (and maybe more efficiently than explicit read/write)	5 years ago

mcellis33	5d15c65e48	Merge pull request #16136 from mcellis33:mec-nan * Handle det == 0 in findCircle3pts. Issue 16051 shows a case where findCircle3pts returns NaN for the center coordinates and radius due to dividing by a determinant of 0. In this case, the points are colinear, so the longest distance between any 2 points is the diameter of the minimum enclosing circle. * imgproc(test): update test checks for minEnclosingCircle() * imgproc: fix handling of special cases in minEnclosingCircle()	5 years ago
