color tracking and masking for multiple objects

    Dec 10 2011 | 12:06 am
    i have a friend who would like a patch that is able to identify all of the red objects in a video and mask everything else in the frame.
    i've used the basic color-tracking features in jitter before, but i'm not sure how to integrate it to work with multiple objects of a similar color or how to make a mask that conforms to the shape, rather than producing a rectangle around the color.
    i know that the objects have some things that might be functional for this purpose, but i'm not totally sure how to implement them.
    any advice would be greatly appreciated. thanks!
