Hi: We are working in a project of "Gaze Tracking". This project have to run in a web browser. We don't have to install any application in the user's computer. Then collect what the user was seeing and send theses point XY to a web server. This is a web based application. Questions:

  • Somebody knows a version of opencv to run in web browsers to run in JavaScript?
  • What about to develop this application in Java and run it in Applet Java over web browser? Is this possible?
  • Any suggestion
  • Somebody want to add to this project?

  • any suggestion, will be appreciate

    Really sorry my English, I'm striving to improve.

    Thank

    Oswald

there will be no way to run opencv in a webbrowser without installing any opencv libs on the client side.

then, since you will have to do your processing on the server side anyway, language does no more matter. (you can do it as well in c++ or python)

well, that was 2015, it's 2018 now, and we got opencv.js

Just my 2 cents - if you dont want to do too much with javascript:

You could also just capture the content of your video frame / canvas / whatever and send it to the server via ajax. Then on the server use the language of your choice (c++ / python / java) and opencv to record / accumulate and return the response as json.
