Maksim Shabunin	008abd28fd	Extracted HAL interfaces for DFT/DCT, added new test	9 years ago
Maksim Shabunin	5877debb6f	HAL resize, warpAffine, warpPerspective interface - added HAL documentation support - added documentation to HAL replacement interface - updated several HAL functions in imgproc module	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.
