\"Face<\/p>\n

In today’s digital age, integrating advanced facial recognition capabilities into applications has become increasingly important for various purposes such as security, identification, and user authentication. Azure Face API provides a robust suite of services enabling developers to incorporate functionalities like face detection, face verification, and emotion recognition into their applications.<\/p>\n

Recently, we faced a requirement to compare two uploaded images and determine the similarity percentage, along with verifying if the faces in the photos belong to the same person. The primary goal was to ensure accurate detection and identification of faces in the uploaded images, yielding precise comparison results.<\/p>\n

In this blog post, we will explore how to leverage the Azure Face API service within Power Automate flow and Canvas App to achieve this requirement. The following steps will guide you through the process of creating an automated flow that validates inputs, detects faces, retrieves face IDs, verifies faces, and ultimately provides a comparison result.<\/p>\n

Step 1: Create an Automated Flow<\/u><\/strong><\/p>\n

Create an Automated flow with the trigger Power Apps(V2). Add two inputs to receive the uploaded images as shown below.<\/p>\n

\"Face<\/p>\n

Step 2: Initialize Two Object Variables<\/u><\/strong><\/p>\n

Add the \u2018Initialize variable\u2019 action in Power Automate to store the content of the first and second images for further use.<\/p>\n

\"Face<\/p>\n

Step 3: Initialize Two String Variables<\/u><\/strong><\/p>\n

Add the \u2018Initialize variable\u2019 action in Power Automate to store the face IDs for the first and second faces for further use.<\/p>\n

\"Face<\/p>\n

Step 4: Validate the inputs<\/u><\/strong><\/p>\n

In Power Automate, add the \u2018Condition\u2019 action to check the inputs received from Power Apps (V2). This action helps ensure that the images uploaded through the Canvas App are properly validated. Within the \u2018Condition\u2019 action, set the values of the \u2018FirstFileContent\u2019 and \u2018SecondFileContent\u2019 variables based on the received inputs.<\/p>\n
