Hello, I am implementing a paper I found for image fusion, and I have come to a roadblock on converting RGB to Intensity and Intensity to RGB There are three methods listed below: I1 = (r + g + b) / 3; I2 = max(r,g,b); I3 = (max(r,g,b) + min (r,g,b)) / 2; But the issue is that they don't describe how to get back to RGB values for any of those equations. The first one is based on smith's hexacone , the second on smith's triangle and the third isn't defined. Does anyone have some advice in this area? Thanks!

Hmm? You're going from a three-dimensional representation to a one-dimensional representation. There will be no way to reconstruct the RGB values without extra information being kept around. If you want a measure of overall light intensity that is part of a reversible color model, check out HSL and HSV.

Yup, these systems are not well defined and quite frustrating. Here is a link to the paper:
