I am trying to call feature detectors from OpenCV
in my C++ application written in Visual Studio. I would like to run this operation in the background and do not care about its timing. Actually, I prefer if it is not interfering with the main performance of the application. To this end, I perform the feature detection in a separate thread and tried to lower the priority of the thread with the command SetThreadPriority()
. This is however not working, and while the OpenCV
function is running, all the CPU cores are maxed out. Is there any way to control the priority of the tasks in OpenCV
or even limit the CPU cores involved in its process?
