This is a nice overview, but needs some editing as I guess this is not the author's first language (but still written better than I could in my second language). The meat of it is there, but I think it needs a once-over from either a native speaker or someone more fluent.

I think there's some content still to be added here:

"After the library is compiled for the smart platform, the last thing to do is call the C API from the target language (Java/Swift)".

On the actual topic, I really like the ability now to take powerful recognition frameworks and put them onto "small" devices. Great work.
