If I need to turn on a camera using front-end webpage, scan an image and see if target image matches pre-defined image. if so, throw a web event.

Is there a JS library doing the job?

thanks

    Should it work offline? For instance, let's say I load your webpage and then board a plane with no WiFi. – Nicolas Raoul May 13 at 9:20
  • @NicolasRaoul not really needed. I just need it to be front-end only – Eric0x May 13 at 10:17
  • Do you have any requirement for the server-side, then? Self-hosted? No budget limit? – Nicolas Raoul May 13 at 12:05
  • no specific requirements. it could be hosted on github.io or any front-end service provider. I have budget, but limit is unknown for now. – Eric0x May 13 at 12:38

I can remember two js libraries Tenserflow & tracking JS. Both can do like webcam tracking, real-time color tracking, face detection etc.

  • can tracking.js do image recognition? like, compare similarity between 2 image? – Eric0x May 23 at 6:33

A little older library is https://github.com/timhuff/canvas-phash. It's a library that uses phash to detect how similar images are.
