Live removal of logos, objects and problems

Ideal to get rid of the odd MacDonalds logo or other unwanted part of a live video image.

That's so cool, and much better than the "fuzzy cup" method you see used on American talent shows

Now they just need to get it to real-time speeds (<2ms) then think of the fun you could have doing corporate jobs, hiding the little things in IMAG.... like the MC's nose - or even better, the CEO of a company when in a wide shot of stage during an awards ceremony... Everyone see's the guy get on stage and shake hands with the CEO, but IMAG shows no CEO... but the timing is still correct.... Make the audience think he is a Vampire....

It IS realtime!

 

Have a look at the youtube clip... absolutely mental!

I suspect it won't remove moving objects but I can see this having huge impact in IMAG none the less, how many times have you suffered from some kind of variation of this problem..

Things are getting really interesting with these kind of techniques - the CS5 background replacement in photoshop is pretty amazing, as is the after effects rotobrush, but this diminished reality thing really trumps them.

40ms delay is not real time (which is what was written on another press release that seems to now 404 on me). In broadcast world, all good, you delay everything anyway, and it is all happy, what's another 40ms. Live IMAG in the corporate world... 40ms additional lag (after you add in your existing infrastructures delays) can make a real difference.

Well in that case 2ms isn't realtime either, its just faster. (realtime would be 0ms - obviously unachievable)

 

40ms is 1 frame of video - If you want to talk about delay in corporate video signal paths then fine but show me a piece of hardware which does anything significant to the video with less than 1 frame of delay. Even an imagepro doing basically nothing at all will add at least 20ms (1 field) of delay!

 

Yes it would not be ideal to have 40ms extra delay on each camera, but its manageable. Anyone shooting on lower end cameras will have this level of delay already from the framesyncs in their vision mixer. By using a genlocked system (and thus losing 40ms of delay from the framesyncing stage) we can now add in this processing and be back at an acceptable 1 frame of delay.

 

Really given what this system is doing 40ms is amazing.

 

On the subject of delay it is always worth bearing in mind how slowly sound travels though the air! In the 40ms of one video frame the sound has only travelled 13.72 meters through the air. Given that IMAG by definition takes place at large events it can actually be advantageous to have some video delay, as this corrects the lipsync for people toward the back of the audience (who are the ones looking at the screens anyway).

 

Anyway the point is that this already offers amazing processing to delay ratio when compared to some of the tools we use all the time for IMAG. Would we like less delay? Of course, but this level of processing in just 40ms is already fast enough to be usable in IMAG systems.
