[GEM-dev] Tracking a specific color

[Matthias Kronlachner]

hi!

use pix_rgb2hsv to convert to hsv colorspace.
then use pix_curve with 3 different tables for hue, saturation and value 
to filter out the desired color.
then convert back with pix_hsv2rgb.
it's a little bit of experimenting with the curves...
