[GEM-dev] Tracking a specific color

[Ricardo Fabbri]

PS: btw, pix_colorclassify actually does exactly what you want. It supports
Greenish, Red-ish, Yellow-ish, Blue-ish, Black-ish and White-ish ;) And it
has been extensively developed and tested using a large database of real
colored paper photos under different
illumination conditions. You may need a very recent GEM.
