I am using the trackers KCF, CSRT and MEDIANFLOW for multiple object tracking(the objects slightly move because of the jerkiness in the video) in a 1920x1080 resolution Video. The fps of KCF is around 30 and the tracking is done quickly(eventhough, it fails at some points.). But, for CSRT and MEDIANFLOW the fps is around 4 and so its very slow( But, very accurate in tracking). Is there any way to change the fps of these trackers? Can someone one please tell, where or how to change it? I am using OpenCV 3.4.1( along with opencv_contrib) in Visual Studio 2015(C++)
