Flow of Model When Using Core ML

The overall flow is very similar for most ML frameworks. Each framework has its own compatible model format. We need to take the model created in TensorFlow and convert it into the appropriate format, for each mobile ML framework.

Once the compatible model is prepared, you can run the inference using the ML framework. Note that you must perform pre/postprocessing manually.

If you want more explanation, check this slide(Korean).

Performance

Execution Time: Inference Time + Postprocessing Time

📏Measure module

You can see the measured latency time for inference or execution and FPS on the top of the screen.

If you have more elegant method for measuring the performance, suggest on issue!
