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
