Is this possible using GEM? For instance converting the visible colour spectrum to a number from 1-10... So if I were to put a yellow sheet in front of a webcam, it would produce a different result to a blue one.

Thanks for any help

i think you can achieve the effect by using [pix_mean_color] and then [rgb2hls] where H is the hue and goes from 0 to 1 according to the color spectrum.

this will obviously give you some pretty rough results, but it should work as a starting point.

Nice one, thanks for that. As you say a starting point, and just to know that in theory at least it is possible, that is great.

Thanks

You must also seek [pix_blob] & [pix_multiblob] for therein may be what you seek.

and also, plug for one of my patches posted here: http://puredata.hurleur.com/sujet-2140-basic-synesthesia

Peace!
