[Azure Trial Hackathon - Face Mask Detector]

Overview of My Submission

This project consists of a mobile application that detects if a person wears a mask or not in a video. It combines the output of 2 Azure AI Cognitive Services:

  1. Azure Video Analyzer
  2. Azure Custom Vision

The application is written in C# using Xamarin, which allows to deliver a cross-platform mobile application that can run in Windows, Android, and iOS among other platforms.

App details:

  • You can record a local video
  • You can upload the video to Azure Video Analyzer
  • You can see a list of videos from Azure Video Analyzer service
  • You can access the details of a video

Azure Video Analyzer service doesn't tell you if you are wearing a mask or not, but it will return frames from the video. That's where Azure Custom Vision enters: Using Object Detection capabilities from Custom Vision project, I could label "mask" zones and "no-mask" zones. Then, I send the frame from Video Analyzer to Custom Vision so it can tell me if the person is wearing a mask or not.
