Tiago De Gaspari	3cf4375387	Merge pull request #19842 from gasparitiago:3.4 Update rotatedRectangleIntersection function to calculate near to origin * Change type used in points function from RotatedRect In the function that sets the points of a RotatedRect, the types should be double in order to keep the precision when dealing with RotatedRects that are defined far from the origin. This commit solves the problem in some assertions from rotatedRectangleIntersection when dealing with rectangles far from origin. * added proper type casts * Update rotatedRectangleIntersection function to calculate near to origin This commit changes the rotatedRectangleIntersection function in order to calculate the intersection of two rectangles considering that they are shifted near the coordinates origin (0, 0). This commit solves the problem in some assertions from rotatedRectangleIntersection when dealing with rectangles far from origin. * Revert type changes in types.cpp and adequate code to c++98 * Revert unnecessary casts on types.cpp Co-authored-by: Vadim Pisarevsky <vadim.pisarevsky@gmail.com>	4 years ago

Aaron Greig	f3f46096d6	Relax accuracy requirements in the OpenCL sqrt perf arithmetic test. Also bring perf_imgproc CornerMinEigenVal accuracy requirements in line with the test_imgproc accuracy requirements on that test and fix indentation on the latter. Partially addresses issue #9821	4 years ago

Aaron Greig	53652a6194	Relax accuracy requirement on OpenCL MinEigenVal corner kernel test. The MinEigenVal path through the corner.cl kernel makes use of native_sqrt, a math builtin function which has implementation defined accuracy. Partially addresses issue #9821	4 years ago
