Algorithm to convert RGB to HSV and HSV to RGB?

I'm trying to find an algorithm (prefferabley represented in C++) that converts from RGBto HSB values so that I can process it accordingly. Anyone got any suggestions?

Solution 1

It's java and not C++ but it should be close enough to be easily reusable. Look for the RGBtoHSB method in this page:

Solution 2

There's a number of colour algorithms demonstrated here, including the one you require which would be worth reading.
