[PD] multiple colour tracking with GEM?

[David McCarthy]

Greetings List,

Is it possible to use several ( pix_movement -> pix_blob )'s to find several
items of the same colour on the screen?

IE if the items were all 'red' and set in a grid form, you could get your white
cube (as in the example patch!) to cover each of these 'red' areas??


Further (!) how would one analyse the percentage of 'red' in these selected
areas!?

Thanks a million :?)

David.
