Reconstructing a reflectance distribution with RGB data

Hello,

I have an excel file with the values of each RGB channel (attachment) and I want to apply the functions available in the article "Numerical methods for smoothest reflectance reconstruction" (https://doi.org/10.1002/col.22437).

Function 1 - http://scottburns.us/wp-content/uploads/2015/04/ILSS.txt

Function 2 - http://scottburns.us/wp-content/uploads/2015/04/LLSS.txt

Function 3 - http://scottburns.us/wp-content/uploads/2015/04/ILLSS.txt

Could someone help me?

Most likely no one is going to do a complete project for you. Who knows, it might take hours. But if you have a smaller, more targeted question about your code, that we could answer in around 5 minutes, then we could probably help. Reply back with your code and your specific question about it.
