Hello, hollance, I run directly your xcodeproj program on my iphone, but I find it delays obviously.I don't know why. Is it because of my cell phone is iphone6 or other reasons. And sometimes identification box drifts.
Now I'm developing a game 【(the game example: https://www.youtube.com/watch?v=Y_TZTnxgD1I
They use infrared technology, and I'm going to use image recognition technology.】which requires very fast image recognition. I hope when press the phone shutter, phone can detect if anybody is in the center of the screen. I learned online that the FPS of yolo was pretty high, but I don't know why it didn't work as well on my iphone. Considering your research in this area, I hope you can give me some advices on development.

At present, I think it is possible to use objective detection（like your program） or direct image recognition, because there is no need to detect whether the camera captures people in real time, but I am not quite clear about it.
THANK YOU!!
