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

Paul E. Murphy	c1cdb2416a	imgproc(resize): improve 8u3 HResize vector exit calc Actually, we can do this in constant time. xofs always contains same or increasing offset values. We can instead find the most extreme value used and never attempt to load it. Similarly, we can note for all dx >= 0 and dx < (dwidth - cn) where xofs[dx] + cn < xofs[dwidth-cn] implies dx < (dwidth - cn). Thus, we can use this to control our loop termination optimally. This fixes #16137 with little or no performance impact. I have also added a debug check as a sanity check.	5 years ago
