I am trying to convert RGB to HSI (hue, saturation, intensity).

I have some formulae to do this, but they are not clear about
what to do when G = B, etc.

Where can I find the exact formulae to do this?
(e.g. all you hackers that have implemented this
in hardware, what algorithms did you use?)

Thanks,

Greg Sorensen
