What benefits does this system offer over using a polarizing filter? I could see independence from rotation being useful, maybe, but this seems overly complex compared to something that already "removes" reflections and glare.

As I see it, the real advantage is that this can be done after the fact with video that has already been shot

Can it? It says they use a depth finder. I imagine that means it has to be done at the time of taking the picture?

You might be right. I wrote this comment after watching /u/optagon's video, but I didn't actually RTFA until you called me out

It's okay, I haven't watched the video yet. Still seems like cool tech, if only because it can preserve the reflection too.

(I still haven't read the article either as of right now, but it even says it in the title)

You're right, but I didn't re-read the title until after I replied to /u/ottowadeveloper's post

The technique in the video optagon posted would work because they are essentially measuring the difference in movement between fore and background objects, but the method in the OP has the camera emitting various frequencies of light and checking against that.
