Chromium team is working to add Shape Detection API to detect faces, bar codes and QR Codes in images.

Currently, Chrome Canary 76 on Android and Windows 10 support these APIs as demo worked for us on these platforms.

For the uninitiated, Shape Detection API is a combination of three APIs: BarCodeDetector, FaceDetector, and TextDetector. According to Chrome Status Page, TextDetector requires Android Device with support for Play libraries installed, macOS 10.11+ and Windows 10.
