Realtime Video masking
Mar 2nd, 2009, 12:06am  
Is it possible to use processing to filter video background in real-time ?

The effect I am trying to achieve is have a quiktime movie with animated characters but the background entirely in a solid colour (white, green,red,etc.)

Can you now load another video or even a graphic and fill the background with the other video or graphic in real-time.

I can achieve this using Photo-editing software one frame at a time where I manually remove the background with a background erase tool and then paste the image as the layer beneath.

Is this possible with processing, in real-time using video and another video or video and images ?

Any help would be really appreciated.

The short answer is yes.  You might run into framerate issues related to:

1.  Removing the background--this depends on your removal algorithm.
2.  Reading two movies from disk at once, but maybe you can cache it in RAM.
3.  CPU load from decoding two movies at once.  Most modern video cards ought to decode on the GPU though.

If these are issues, you can try using smaller resolution movies.

Due to your request, if there wasn't before, there is now.

Warning: shameless plug ahead!

It uses JMF rather than the usual video library.
If you have any questions, let me know.
