is cv::Mat ref counter atomic?
I have global variable cv::Mat a
, then I'm trying to read access two different parts of a
from 2 different threads using ROI indexing: cv::Rect r; const cv::Mat tile = a(r);
. Will this type of access create race conditions if I only do read on tile
? In particular, the ref counter in a
will increment with each such access, is this counter an atomic variable, won't it create a race condition?
