CoreML object detection model can be used in iOS, tvOS, WatchOS and MacOS apps. This video contains step by step tutorial on how to train object detection model using CreateML and then how to use it in iOS app. You will learn how to collect data, how to label it and then how to use CreateML to train object detection model. In last step i present how can you use trained CoreML model in simple iOS app to predict location of objects on photos.

It is a nice tutorial, but could you make one for making CoreML applications for MacOS? Or maybe also in C++/ObjectiveC? Is there much difference? It drives me mad that obviously we know that CoreML is for MacOS but most tutorials point you to building CoreML applications for iPhone, as if all people were supposed to be do just that. While clearly doing CoreML applications for Mac is a valid task

Xcode indicates that the file "Road Sign Object Detector 1.mlmodel" has prediction outputs of "confidence" and "coordinates", and I got these values successfully in the JSON of prediction result. However, I would like to include"label" description in the JSON prediction result. Do I have to rebuild the .mlmodel file?

You don’t have to rebuild model, you can simply use prediction json output and create new jaon based on that, with any additional field you want, like label.

Hello Tom and thanks for providing this tutorial I encountered an issue using your trained model and also with my own separate retraining. Problem is during Preview/testing. If the test image is large (e.g. 640x480), road sign detection is perfect. But if the image is small (e.g. 320x223), the rectangle for the detected road sign is in an incorrect location. But the rectangle is in the correct location if the image were to be zoomed to a larger size. Image 2, Image 6, image 4 are failing. Others are perfect You can inspect the image sizes in Preview (inspector). Using preview, When I use a zoomed in version of these images it appears that the detector rectangles are in appropriate location for the zoomed in version (eye-balling it from Preview). Why is this happening ? It appears in my version of Create ML there is a minimum image size. I use a 2018 MBP, Create ML 2.0 (53.6), Xcode 12.5.1

@tom The output was 60+mb for such a small sample, increasing the app download size by ~60MB might not work in most parts of the world. What's your take on that?
@TomBaranowicz

The output from CreateML, or size of the app? Apple compresses models when added to XCode, so it's possible that the overhead will be much smaller.
