atinfinity	e4f207c4b4	Changed cv::threshold() to support CV_64F	9 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

ohnozzy	9be6b4f2d1	Bug Fix for 6377 Rewrite linearPolar & logPolar so that they do not depend on the deprecated API CvMat. Issue 6377 is resolved in this way because the two routines do not convert UMat to CvMat anymore.	9 years ago

Maksim Shabunin	a5af69de6a	Java wrapper for moments: do not truncate values in set method	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

Leonid Volnitsky	bebab8d647	fix: 6149 (through CV_Error on wrong image type)	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.
