I actually figured out the issue with loading the face recognizer! I had to find the app-specific path to the file first.

I’m creating an iPad app that takes video from the front cam and for each frame detects a face and categorizes the emotion.

Running the app, though, I’ve found that many frames are dropped (I can only get about 2 frames every 30 seconds). Any suggestions as to which functions are slowing it down and how to improve performance in general?

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
