Tomoaki Teshima	ba73249dc0	let the test of AccSqr_SIMD<ushort, float> pass ... * The difference becomes too large when multiply is done in int16 * To reproduce the test failure, IPP has to be switched off	9 years ago
Alexander Alekhin	f2e41ce391	ocl: fix input data for Canny perf test ... "declare.in(img, WARMUP_RNG)" overrides input image with random values Also added support for different input sizes (via cv::resize)	9 years ago
Alexander Alekhin	b8e08d5d3c	ocl: fix Canny for Intel devices ... There is an issue with processing of abs(short) function for negative argument. Affected OpenCL devices: - iGPU: Intel(R) HD Graphics 520 (OpenCL 2.0 ) - CPU: Intel(R) Core(TM) i5-6300U CPU @ 2.40GHz (OpenCL 2.0 (Build 10094))	9 years ago

mschoeneck	5f30a0a076	Merge pull request #6958 from mschoeneck:Common-Canny-parallelization ... * Common Canny parallelization added. TBB and single thread code removed. Final pass vectorized with SSE2 intrinsics. * wrong #ifdef replaced with #if * Merged to actual Canny version * Merged common parallelized Canny with actual Canny implementation * Remove 'Mutex *mutex' and pass 'Mutex mutex' from outside to parallelCanny * Replaced extern Mutex with intern mutable Mutex.	9 years ago

Matthew Self	72672c293f	Make goodFeaturesToTrack() return deterministic results ... When using OCL, the results of goodFeaturesToTrack() vary slightly from run to run. This appears to be because the order of the results from the findCorners kernel depends on thread execution and the sorting function that is used at the end to rank the features only enforces are partial sort order. This does not materially impact the quality of the results, but it makes it hard to build regression tests and generally introduces noise into the system that should be avoided. An easy fix is to change the sort function to enforce a total sort on the features, even in cases where the match quality is exactly the same for two features.	9 years ago
