Hello,

I am using the brightness function and adjoining that with video. The result is small blue pixels in the areas of motion. Right now I am not voiding the background- and as a brightness function the only thing that will show is the motion.

My question is if it is possible to enable the blue pixels to be drawn but not voiding the black background common to the brightness function, so there is a buildup of images and shows the video's subject's motion.

thanks!

To get an aggregate drawing, usually all you need is to remove the background call from your sketch.

However in this case perhaps the black and blue are both part of the 'image' displayed on each draw cycle.

In that case you could for example only draw pixels above a certain threshold or of a certain color. Definitely possible.

Anyway, when you post some code, it's easier for us to help you with this.
