Hi, I study face tracking recently, and I find your code. I want to use your code on the phone, so the speed is important for me, but the time of my study is limited, so I want to know the fps of process on Andriod or IOS. Would you mind tell me? Hope your reply. Thank you very much.

Hi, I can give you some timings for the eos library. With the 3448 model, it's currently about 30 ms or so per iteration, with the 845 model, around 3 ms. I optimised the model's visibility check locally and got that down to 3 ms and <1 ms respectively - will try to commit that in the next couple of months. These timings are on a i7-7700HQ, using mostly 1 thread. As always with performance questions: The profiler is your best friend.
