VisionWorks sample for face detection (not opencv)

Hi,

I think 10FPS is already near the best performance on tk1.

Sharing some tuning experience for you:

  1. maximize frequency:
sudo ./jetson_clocks.sh
  1. Downscale input image:
    We usually downscale image to 640x360, but this depends on use-case

  2. Enlarge upscale parameter

cascade_gpu->setScaleFactor(1.2);
