I used the link above for detection of a colorchecker in an image.
I am wondering about two things.
1) Is it possible to make the boxes bigger to cover more area in each colour patch?
2) In the Table T, what does the reference (L a b) mean? Does the reference mean those data are coming from measuring the colours physically with a spectrophotometer? Or does the reference mean those are the standard data available online or from XRITE offical website?

You could pass a different value for Sensivity to colorChecker. By default it is 0.6.
