I hope to disscuss about "how to improve the efficient of the code?"

3000FPS is mentioned in the paper.But I run the code to test the efficient.The code deal with 224 images needing 5 minuters.I feel the efficient cann't meet our need.I feel training random forest need a long time.But I don't know how to improve it. What's more, the code run needs what conditions to the hardware? Meanwhile, I hope you can give me some directions. Thanks very much!
