Is there any ways to make it realtime?

even after moving out for 1 minute, it is still recognizing...

++ same issue here. Would be nice to hear authors comments on this.

@hxdef2517 rewriting the evaluation function and the filter, I have managed to make it accurate. Threading does the magic of making it real-time. Now that it works accurate as well as real-time.

@Zumbalamambo please let me know how did you rewrite the evaluation function and filter,it would be
helpful if you can mail me

@Zumbalamambo how did you make it .

I also see accuracy issues. Even with house lights turned off, the signal seems to consistently hover around 60Hz, when I'm seeing 70-100 on a finger pulse oximeter.
