How about performance? #7

Hi, Thanks for this implementation. I would like to know if there is any performance gain using this implementation compared to author's implementation when dealing with relatively large number of trackers(say tracking 100 objects in single instance)??

  1. This is a part of the actual project. I remember that when I changed it, the performance would be better than that of the author. As for how much, there is no specific data.

  2. I used the HOG feature in the actual project, the speed is much faster than the original.

  3. After adopting the HOG feature, we tested that the 8-core(i5) CPU can drive the target tracking of 80 people. 50ms one frame. We use frame buffer to make video stream smooth.

  4. Sorry, no specific comparison data.
