Custom Vision Service lets you export your classifiers to be run offline. You can embed your exported classifier into an application and run it locally on a device for real-time classification.

Custom Vision Service supports the following exports:

Important

Custom Vision Service only exports compact domains. The models generated by compact domains are optimized for the constraints of real-time classification on mobile devices. Classifiers built with a compact domain may be slightly less accurate than a standard domain with the same amount of training data.

For information on improving your classifiers, see the Improving your classifier document.

Note

The steps in this section only apply if you have an existing model that is not set to compact domain.

To convert the domain of an existing model, take the following steps:

On the Custom vision website, select the Home icon to view a list of your projects.

Select a project, and then select the Gear icon in the upper right of the page.

In the Domains section, select one of the compact domains. Select Save Changes to save the changes.

Note

For Vision AI Dev Kit, the project must be created with the General (Compact) domain, and you must specify the Vision AI Dev Kit option under the Export Capabilities section.

From the top of the page, select Train to retrain using the new domain.

To export the model after retraining, use the following steps:

Go to the Performance tab and select Export.

Tip

If the Export entry is not available, then the selected iteration does not use a compact domain. Use the Iterations section of this page to select an iteration that uses a compact domain, and then select Export.

Select your desired export format, and then select Export to download the model.

Integrate your exported model into an application by exploring one of the following articles or samples:
