Quickstart - Analyze Face

Overview

The purpose of this guide is to help you create a working sample of the Analyze Face activity. This working sample enables you to quickly verify the connection to your AWS account and get familiar with the activity's input/output datatypes.

By completing the steps in this guide, you'll have an automation sequence that does the following:

1. Establishes a connection to your AWS account and Amazon Rekognition service via the Amazon Scope activity.
2. Detects faces in an image and returns information about the face via the Analyze Face activity.
3. Tests the Amazon Rekognition activities' input/output properties via the For Each and Write Line activities.

Prerequisites

Before you begin, complete the applicable prerequisites below.

If you've completed the prerequisites for a different Amazon Rekognition Quickstart guide, you're all set and can go straight to the Steps section below.

1. Complete the Amazon Rekognition Setup steps.
2. Create a new automation project.
   1. Open UiPath Studio.
   2. Under New Project, click Process (this opens a New Blank Process window).
   3. Enter a project Name, Location, and Description.
   4. Click Create.
   
   

   

   
   
3. Install the UiPath.Amazon.Scope.Activities and UiPath.Amazon.Rekognition.Activities packages.
   1. In the Design ribbon, click Manage Packages (this opens the Manage Packages window).
   2. Under All Packages, click Go!
   3. In the Search bar, enter Amazon.
   4. Click, install and accept the license for both the UiPath.Amazon.Scope.Activities and UiPath.Amazon.Rekognition.Activities.

Steps

Build Your Project

1. Add the Amazon Scope activity to your project.
2. Add the Analyze Face activity after the Amazon Scope activity.
3. Enter the ImagePath or ImageURL of the image that contains the faces you want to add to your collection.
   • Recommendation: create a String variable for your image location so that you can reuse it in other activities (e.g., Identify Faces, Compare Faces).
4. Create and enter a FaceDetails[] variable for your FaceDetails value.
   • When creating your variable, select the UiPath.Amazon.Rekognition.Models.Face[] variable type.

Test Your Project

1. To test the Analyze Face activity, add a For Each with a Write Line activity.
2. In the TypeArgument property, select UiPath.Amazon.Rekognition.Models.Face.
3. In the Values property, enter the FaceDetails[] variable you created in step 2 above.
4. In the Text property, enter the face details that you want to return (e.g., item.Beard.Value.ToString returns a Boolean value for each face identified in the image).
   • For more information, see FaceDetails under the Analyze Face activity's Output section.
5. Click Run and verify the Output window includes the face detail values you entered in the Write Line activity.

You're done!

When you're ready, try the other Quickstart guides to get more familiar with the different Amazon Rekognition activities.
