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))	8 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.	8 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.	8 years ago

ohnozzy	db9f611767	Add OpenCL support to linearPolar & logPolar Add OpenCL support to linearPolar & logPolar. The OpenCL code use float instead of double, so that it does not require cl_khr_fp64 extension, with slight precision lost. Add explicit conversion Add explicit conversion from double to float to eliminate warning during compilation.	9 years ago

themightyoarfish	68d97502fe	Error message for wrong kernel size was insufficient. When setting a wrong kernel size, the error message only tells the user that it must be odd, however the conditions for rejection include values > 7 which must be communicated. Without that, the message would be incorrect and confusing if the user is unaware that only values 3, 5, 7 are accepted.	9 years ago

Zhigang Gong	0b08d2559e	fix potential race condition in canny.cl. See the below code snippet: while(l_counter != 0) { int mod = l_counter % LOCAL_TOTAL; int pix_per_thr = l_counter / LOCAL_TOTAL + ((lid < mod) ? 1 : 0); for (int i = 0; i < pix_per_thr; ++i) { int index = atomic_dec(&l_counter) - 1; .... } .... barrier(CLK_LOCAL_MEM_FENCE); } If we don't put a barrier before the for loop, then there is a possiblity that some work item enter this loop but the others are not, the the l_counter will be reduced in the for loop and may be changed to zero, and the other work items may can't enter the while loop. If this happens, it breaks the barrier's rule which requires all the work items reach the same barrier. And it may hang the GPU depends on the implementation of opencl platform.
