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
103yiran	6e6c0f31f7	delete unused variable	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
