movement painting

Hi everyone!!!!

Anyone can give me a hint on how to achieve the effect at the beginning of this clip

http://www.youtube.com/watch?v=FNa7qITtdgM 00:21 and on

I’ve been fooling around with the jit.slide and compositing for the background but cannot get the colors on the black background.

thank you for your help

I would go a different route. Look into the cv.jit external objects. http://jmpelletier.com/cvjit/

You can use the running average to do something similar to what you have in mind. But the action must move slowly and will fade over time. play around with it.

Hi Adam thanks for your answer !

Isn’t the running average the same thing that the jit.slide but optimized ??

what I still can’t do is having the black background and only let the trace of the slide or the running average to stay in the showing window…

do i have to use some sort of mask to get to that?

thanks

Hi
Maybe do a forum search on background subtraction -
One approach is difference the slide with the input than overlay on background . . .
Cheers
