Running an Object Recognition in PowerApp with many images

Posted on by Pierre-Quem

Dear all,

I developed a simple clothing color detector based on the AI builder. However, I can only run it one image at a time and the previously analysed result is not saved (pictures below).

Is it possible to run the detector on a set of images (20+) and have the result of the analysis directly displayed below?

Thank you,

Pierre

Hi,

One way to do this is to create a Power Automate flow that will batch process your new images on a regular basis (for instance using the "When an file is created" trigger) and store the results of the prediction in a Common Data Service entity.

Then you can your Power App displaying these results.

Hi @CedrickB,

Thank you for you answer.

That's what I was guessing but I can't find any documentation or use cases explaining how to deal with that. Do you have any idea where I could get some?

Regards,
Pierre

Hi @Pierre-Quem i:
I spent almost a whole day doing the test.
I can almost be sure that canvas app should not be able to achieve this function.
In addition, flow can do this, but it can't return the results to your canvas app.
Firstly, let me explain why the value of flow cannot return the value to the application.
Only the flow in the solution can use Predict action (AI). Prerequisites for using AI Builder in Power Automate
But Canvas app triggered flows are not available in solutions. Known limitations
Secondly, If you are interested in using flow alone, this is my solution:
My data source: pictest

Add a new flow in a solution.

Restult:

Best Regards,
Bof

To bofeng this solution, instead of sending by email you can simply store the result in an entity in the last step with the Power Automate action "Create record" of Common Data Service.

Then you can browse this entity in a Power App with a simple "Display form".

Here is a documentation on how to call the object detection from Power Automate https://docs.microsoft.com/en-us/ai-builder/object-detection-model-in-flow

And here is how to create a view form on top of an entity https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/controls/control-form-detail

Note that the limitation of calling the Power Automate "Predict" action in a solution is been removed in coming weeks.

We are also adding named actions with improved ease of use to call AI Builder from Power Automate for each model (Call an Object Detection model, a form processing...) in May.

Hi @v-bofeng-msft, @CedrickB

Thank you for all your feedbacks and the example you provided. Thanks to your help I've managed to run my object recognition system in a flow and I can display it on my PowerApp with the form.
