Analyze User Profile Photos using Azure Computer Vision API¶
Author: Joseph Velliah
This script uses Azure Cognitive Service API and Microsoft 365 CLI to analyze user profile pictures and assess whether they meet the standards placed by the organization. It can be customized to ban content within an org channel or collaboration network where employees post pictures, memes, etc.
Prerequisites
- CLI for Microsoft 365
- Microsoft 365 users
- Computer Vision API instance and API key
Note
If you don't already have an Azure Cognitive Services instance and key, create a cognitive service instance and get API key from there.
