• Now, you will need to select the domain for your Model. AI Builder provides 3 special domains.
  • Common Objects – This domain is selected by default. And, can be used if your requirements don’t fit in the below domains.

• Now, click on the “Next” button and add the object names you want to detect from the image. You can also select from the database. Then click the “Next” button.

• Then you will need to upload the sample images to train the model. It will need at least 15 sample images of each of the objects to be detected. Click on the “Next” button.

• Then, you need to tag each of the objects. For that, click on the object and select the Object name for it. Then click on the “Done tagging” button.

• Publish the Model and now the Object Detection model is ready to be used in the PowerApps, Power Automate, etc.

• Now, let’s see how can we use this Object Detection Model in the PowerApp with a small example.
• For that, let’s create a new Canvas PowerApp.

• Now, select the “Object Detector” tool from the “AI Builder” toolset.

• Then, select the above-created Object Detection Model from the list.

• Now, let’s place a gallery on the PowerApp screen to display the object Names in the image along with the count of each object. And, set the “Text” property of the gallery Title and Subtitle  as follows:-

Title = ThisItem.displayName

Subtitle = ThisItem.count

• Now, click on the “Run” button and then on the “Detect” button.

• Now, a popup will be opened. Select the image from which the objects are to be detected. And, you will see that the count of each object is displayed on the screen.
